The 'Lab Leak' Inquiry at the State Department
Anyone who cares about ensuring that the lab-leak hypothesis is taken seriously should probably be thanking me, rather than vilifying me.

The following essay was originally posted at the authorâs Medium blog here.
In both journalism and policymakingâif not always in politics, or in the sordid world of score-settling by unemployed, second-rate apparatchiksâfacts matter, and intellectual integrity matters. In light of the remarkable quantity of errant nonsense that has been written in the last couple of weeks about squabbles inside the US State Department about how to look into the origins of SARS-CoV-2 in the closing weeks of the Trump Administration, I hope this essay will help set the record straight for those who still care about things such as facts.
I write this because, to put it bluntly, Iâm tired of being the butt of stupid and paranoid conspiracy theories being promulgated by those who know better. I recognize that some of these conspiracy narratives are, for any thoughtful person, self-refuting even on their face. (As someone who has been warning the policy community since at least 2007 about threats to the United States and the democratic world from the Chinese Communist Partyâs geopolitical ambitionsâincluding in two scholarly books and scores of articles and speeches, including in official capacity at the State Departmentâhave I been âprotectingâ the Chinese Communist Party from accountability? Good grief.)
Nevertheless, Iâve been around politics long enough to know that an imbecility that slots into a convenient narrative beats an awkward fact any day, and manic performative outrage is much more fun than sober analysis. So perhaps offering clarity here wonât change a thing. Yet Iâm still going to try.
Iâm also going to try to do something unorthodox here. Rather than using this essay as an opportunity to invent and loudly dispense my own post hoc version of what happenedâa dishonest revisionism-of-convenience that is in abundant supply, but that I will leave to othersâI will try to offer you only specific claims that are supported by contemporaneous documents that enterprising journalists at Fox News and Vanity Fair have recently put into the public record.
A clear documentary record
In particular, since the question at hand is my own particular role and position in connection with investigating the origins of the SARS-CoV-2 virus, I will refer to three unclassified documents that I myself wrote and sent to others at the State Department in early January 2021. (For the record, I did not retain these documents when I left the Department. Thankfully, howeverâat least for meâsome of the lies being told on these topics have apparently caused offense among those who know what really happened and clearly did retain the documents.) Iâm happy to see them in the public record, because they make very clear exactly what I was doing at the time, and why.
The documents are as follows:
- An email I sent to Tom DiNannoâthe Deputy Assistant Secretary who was at the time serving as Senior Bureau Official in the Arms Control, Verification and Compliance (AVC) Bureauâand to AVC consultant David Asher on January 4th, 2021, which can be found here thanks to Fox News.
- An email exchange between me and DiNanno on January 5thâ6th, which can be found here thanks to Fox News.
- A message I sent to a number of senior State Department officials on January 8th, which can be found here thanks to Vanity Fair.
Pushing for an honest and defensible lab-leak inquiry
So, let me begin with a critical point. As detailed in these documents, the squabbling at the State Department was about trying to ensure that we got our facts straight before going public with dramatic steps such as having Secretary Pompeo announce that it was âstatisticallyâ impossible for SARS-CoV-2 to be anything other than the product of Chinese government manipulation, sending âdemarchesâ to foreign governments with this theory, or writing up China for having violated the Biological Weapons Convention (BWC) in connection with COVID-19.
The dispute had nothing whatsoever to do with trying to quash investigation into the origins of the virus, and everything to do with trying to ensure the honesty and intellectual integrity of that investigation precisely because it was vital for us to get to the bottom of the question of COVIDâs âorigins,â including the possibility that it came from the Wuhan Institute of Virology (WIV). I strongly supported looking into the âlab-leakâ hypothesis, which clearly is a real possibility.
But Iâm not just saying this now. I said it at the time, too. A lot.
Letâs look at the documents, starting with my January 4th email to DiNanno and Asher. In that message, I highlight that AVCâs scientific âallegations about WIV and Chinese BW work allegedly being the sourceâ of SARS-CoV-2 were âimportantâ and âworrying,â and that these significant claims needed to be evaluated by real scientific experts.
(Yes, I admit that I called the virus the âWuFlu.â At a time before the World Health Organization had come up with ânon-stigmatizingâ designators such as âAlpha,â and people talked freely about things like the âUK variantâ or âSouth African variant,â it didnât seem unfair to tag the original virus as having indeed come from Wuhan. Iâm afraid at another point I called it the âKungFlu,â too. None of this sounds as clever to me in retrospect as I fear it did at the time. But please remember that these were internal emails, not intended to see the light of day. Had I written these messages with an eye to public release, I would not have been so glib. Mea culpa.)
In my email, I reminded DiNanno and Asher that I had directed them, a month or so earlier, to establish an âexpert vetting group or processâ that would involve real scientists and intelligence experts in assessing the strength of AVCâs claims. But why, I asked them, had there been no progress in subjecting their assertions to peer review? And why were they running around the interagency spreading these allegations before we knew whether these claims could pass muster with objective, third-party scientists?
As I stated in that January 4th message, I wanted to demand âmore transparency from the PRC here, especially in light of their appalling early cover-up of COVID-19 during the early weeks when honesty and resolute action could have made such a colossal difference in heading off millions of deaths and untold suffering, and in light of their grotesque history of such cover-ups.â
âAn investigation of [COVID] origins is very important,â I reiterated, âand Iâm delighted to press their feet to the fire for the honesty and clarity theyâve so far refused to provide.â However, I also stressed how important it was that we get our facts straight before going public as the US government with the accusation that the Chinese government created the virus:
[W]e need to make sure what we say is solid and passes muster from real experts before we risk embarrassing and discrediting ourselves in public. ⌠As I have repeatedly said, if it turns out that your conclusions are right, Iâll happily be first in line to scream from the rooftops about them, for it would be a colossal outrage. And you may well be right. But I want to be confident about where the facts really lie. ⌠These issues are surpassingly important and we need to get to the bottom of themâbut rigorously, defensibly, and truly.
Hence my annoyance, expressed in that message, that DiNanno had been dragging his feet over my direction to âarrang[e] expert-level bioscience and intelligence vetting of David [Asherâs] work.â I warned DiNanno that such dithering looked bad: âPlease donât continue to feed the impression that AVC is afraid of peer review.â And I insisted that he tell me when they actually planned to get those allegations vetted by real scientists. Itâs all there in the email.
The next day, January 5th, when I still hadnât heard back from DiNanno about how they would ensure that their scientific assertions got evaluated by actual scientists, I emailed him again. (This was the message at the bottom of the January 5thâ6th email string Fox News published.) Iâll admit I was grumpy, but I think I was also pretty clear about my focus on ensuring that we got our facts straight on this critical issue of COVID origins:
It is ⌠becoming embarrassingâand, if I may say so, more than a little worrisomeâthat AVC seems still to be ducking an expert-level engagement to evaluate its own WIV allegations, even while it has continued, over the last month or so, to brief its claims to non-experts across the interagency.
DiNanno responded to my January 5th message with platitudes about how all they were doing was âinvestigating potential arms control violations.â (This is the middle message in the January 5thâ6th string.) âThat Is [sic] exactly what we have done,â he declared, âand will continue to do.â
Letâs pause here for a moment. If youâre paying attention, youâll have noticed that with this comment about âinvestigating potential arms control violations,â DiNanno signaled that AVC regarded itself as focusing not so much upon the origins of SARS-CoV-2, per se, as more specifically upon China allegedly having violated the Biological Weapons Convention by creating the virus. They seemed to believe that COVID-19 was a biological weapons (BW) effort gone awryâor perhaps even a BW agent deliberately unleashed upon the world after Beijing had secretly vaccinated its population, as Asher has rather remarkably suggested in public now that the State Department has terminated his consultancy contract. (You can see him in all his sober, cautious, and methodical glory on YouTube.)
In this context, I suppose it was hardly surprisingâas I memorialized in my January 4th email to DiNanno and Asherâthat in the December briefing when AVC first pitched me on their WIV-origins theory, Asher at one point suggested that SARS-CoV-2 might be a âgenetically selective agentâ (GSA) that China was using to target us, as evidenced, he said, by the fact that Sub-Saharan Africa wasnât reporting many COVID cases while the United States was. (Surely you donât need me to spell out how that notion was both analytically unsupportable on its face and contained deeply offensive implications, do you? Iâll leave you to work this out on your own, but, uh, wow.)
Fortunately, however, DiNanno also informed me in his January 5th response that AVC had now indeed set up a panel of experts to discuss the scientific claims, which would occur on Thursday evening, January 7th. (Finally! As noted in my January 4th email, Iâd been demanding expert vetting of AVCâs âstatisticalâ argument since they first came to me with this issue in my office in December.) As this panel approached, however, I wrote DiNanno againâon January 6thâto emphasize how important it was that we get real scientists to vet AVCâs allegations before we surfaced such dramatic claims in public:
As I indicated before, having something that sounds scientific to say when making assertions to laymen is not the same thing as being correct. I do not have the scientific expertise to critique Davidâs claims. Nor do you. Nor, in fact, does he have actual technical training in the first place. That doesnât necessarily mean heâs wrong, of course, but it does have implications for how to deal with the complex and controversial claims you guys are making about weedy bioscience.
[âŚ]
If youâre right, you should be willing to prove it, and to confront experts whoâunlike all of the people involved in building and making this argument for youâactually have training in the scientific field about which you make assertions. I really donât know how I could possibly have been more clear about this over the course of the last month. Your allegations are dramatic, and potentially very significant indeed, but itâs for precisely that reason that they need to be tested and evaluated carefully.
[âŚ]
Your claims need to be assessed by real expertsânot just waved around as bullet points on slide decks in front of non-scientists who are then dared to prove you wrong.
It was particularly important to get real expert-level assessment of the scientific assertions AVC was making about laboratory origin because the AVC investigation appeared to have carefully bypassed State Department expertsâboth in my own bureau and in AVC itself, each of which has a whole office devoted to such questionsâand the US Intelligence Community. As I recounted in my January 8th message, âAVC ha[s] apparently been briefing this argument inside the Department and [to] some interagency partners for some weeks, apparently on instructions from a staffer at S/P [the Departmentâs Office of Policy Planning] who told them they should not inform me or others of this work, nor involve the Intelligence Community.â

(A footnote, but perhaps a significant one: That last bit about cutting real experts out of the loop came to me directly from Tom DiNanno. When I asked him why AVC had been doing all this without telling the senior official to whom they reportedâthat is, meâhe told me sheepishly that he had been instructed to do things this way by Miles Yu, an S/P staffer at the time. According to DiNanno, Yu had represented that these specific instructions came from the Secretary. DiNanno, then in charge of the verification bureau, gave no sign of ever actually having verified that this was true, however. He appeared to have accepted Yuâs representations at face valueâin effect, a de facto Assistant Secretary of State taking marching orders from a lower-ranking staffer in another bureau, sight unseen. It would be interesting, now, to find out whether: (1) Secretary Pompeo really directed that AVCâs lab-leak inquiry avoid engaging Departmental BW experts and US intelligence officials, and that it do its work essentially in secret, without telling the official performing the duties of the Under Secretary for Arms Control and International Security; (2) Yu was, at least in this respect, dishonestly freelancing; or (3) DiNanno was just lying to me about his conversation with Yu. Perhaps a good journalist can go figure this out.)
The scientific panel
Anyway, at least a first chance for scientific vetting came on January 7th, when the panel of experts picked by the AVC Bureau had a chance to discuss the âstatisticalâ proof that AVC had been relying upon in its assertions to me and others that the SARS-CoV-2 virus had to have been the product of Chinese government manipulation.
Unfortunately, as I memorialized the next day (January 8th), despite my urgingâin the last three paragraphs of my January 6th emailâthat the other members of the panel âhave ⌠the benefit of actually being able to read the paper beforehand,â AVC had not shared the document ahead of time. As I observed on January 8th, âAVC did not provide us with the actual paper before yesterdayâs discussion, so most other participants had not had the chance to study it in detail.â
Even so, it did not take the other panelists long to point out some key flaws in the âstatisticalâ argument, which had been presented orally to the panel by the scientist upon whom AVC had apparently most relied in developing that line of argument. (His name is widely known, but I opted not to single him out in my message to Departmental colleagues. I felt that scientists should have some freedom to figure out the science amongst themselves; my concern was with what the US Government would assert after they did. Rather than drag him personally into the fray, therefore, my memo reflected the fact that this manâs claims had effectively become AVCâs argument as the bureau promoted them in the interagency.)
Iâll spare you the blow-by-blow of criticisms made by other panelists about the âstatisticalâ case AVC had been making at least since the first briefing they gave me in my office in December, though you can read the salient details in the January 8th message I sent to a number of my senior State Department colleagues the next day. (My message focused on the statistical argument, given the prominence it had enjoyed in AVCâs briefings; I did not purport to summarize the panelâs discussion of all matters raised.) As youâll see if you care to read my several-page account on January 8th, the assertions AVC had been making seemed to have major problems. At the least, those assertions were clearly not yet ready to be the official position of the US Department of Stateâwhich is why I sent that January 8th message warning my colleagues to be careful about running with that particular âstatisticalâ claim.
I also now know, thanks to Vanity Fair, that DiNanno responded to my January 8th memo with one of his own a day or two later, after I had left the Department. The reader can find it online, so I wonât walk through it here. In light of what you now know from documentary evidence about my actual positions at the time, however, youâll easily be able to see what a pack of distortions and falsehoods DiNannoâs memo actually was. You might want to lay our two documents side by side and read them carefully in light of the information you now have. I suspect it will be pretty clear that his memo was a dishonest mess of baseless attacks on meâan angry screed addressed to readers whom DiNanno knew did not have the benefit of knowing what Iâd actually been saying to him for the last month, and which he sent to his readers at a time when he knew I had resigned from the Department and would have no chance to defend myself and correct the record. (Thankfully, however, our bosses were intelligent folks. One can probably infer how seriously our superiors took DiNannoâs memo by the fact that they apparently acted on my note of caution about AVCâs scientific claims rather than on DiNannoâs shrill and convoluted attempt to defend those assertions and paint me as the villain. More on that below.)
For the purposes of this essay, Iâll leave the issues of science to any of you who are scientists. As I told DiNanno in my January 6th message, âI do not have the scientific expertise to critique Davidâs claims. Nor do you. Nor, in fact, does he have actual technical training in the first place.â That is precisely why I insisted that AVC set up a panel of experts, and whyâafter they finally got around to arranging this peer review on January 7thâit was my duty to convey to my colleagues some of the concerns raised by the experts AVC had put on the panel. It may in the end turn out that science does prove that SARS-CoV-2 was the result of human intervention at WIV. But it would have been grievously irresponsible for us to adopt that theory publicly until it was much more able to stand on its own two feet that the January 7th panel discussion showed it to be at the time.
Putting absurd accusations to rest
Some of my former colleagues are nowâperhaps, one imagines, out of embarrassment over all of the events described aboveâasserting that I tried to prevent inquiry into the lab-leak hypothesis and to shut down any investigation of the question. (Thanks to Tucker Carlson making this claim at least twice on the air, by the way, Iâve now gotten vicious and deranged hate mail. Hereâs, for instance, what I received on June 3rd after Carlson first mentioned me on his show: âFuck you dickbag globalist shill. Why the fuck did you shut down the lab leak theory? Go lick some China communist boots.â)
Yet no serious person who is actually aware of my interactions with AVC could possibly think I wanted to prevent inquiry into the laboratory hypothesis, as you will already have seen from my emails of January 4th and January 5thâ6th, from which Iâve quoted extensively here. You can also see that I was always crystal clear about the importance of getting to the truth by fully investigating the laboratory-leak question, making clear that âif it turns out that [AVCâs] conclusions are right,â I would myself âhappily be first in line to scream from the rooftops about them.â
Additional proof of my commitment to looking into WIVâand indeed my focus upon protecting efforts to investigate the laboratory-leak question from the discredit and ridicule that might have smothered it in its crib if we had foolishly hitched Secretary Pompeo, the Department of State, and the Administration to easily debunkable junk scienceâcan be found in my January 8th message itself. There, I made the point yet again:
If well-founded, AVCâs findings would be extremely significant. ⌠All participants [in the January 7th panel] seemed ⌠to agree that China should be pressed for answers about such things as the nature of any work done at WIV on novel coronaviruses, whether any safety incidents occurred, what data is in WIVâs sequencing database (which was mysteriously taken offline early in the pandemic), and when exactly the PRC realized (despite its early representations) that SARS-CoV-2 was only in its âwet marketâ environmental samplesâand not in its live animal samplesâleading them to conclude that the market was not the source of the outbreak. These sorts of questions should indeed provide us with lots of grist for pressing China for answers and highlighting its non-transparency and history of failing to report (or even covering up) critical information.
Youâll also see from my January 8th message that I specifically directed âAVC and ISN [the International Security and Nonproliferation Bureau] to collaborate on drawing up a list of questions and points that could be useful in this regardâ in pressing Beijing for answers. So were these the actions of a âdickbag globalist shillâ who âlick[s] ⌠China communist bootsâ? Or of a serious steward of the honesty and intellectual integrity of US State Department policymaking dedicated to ensuring we got our facts straight and pushing back against recklessness that would make it harder to have the lab-leak issue taken seriously? The reader can make up his or her own mind.
A net assessment
So where does that leave us now?
Well, if you want to understand what I was trying to do during this period of bickering inside the State Department, you now have my own words from internal contemporaneous records. Simply put, I felt it would be essentially insane to go public with AVCâs scientific assertionsâsuch as, as DiNanno and Asher had urged, making public statements, demarching foreign governments (including China), and finding China in violation of the Biological Weapons Convention over this coronavirusâbefore getting those scientific assertions vetted by objective, third-party scientists.
Let me be completely clear: From where I was sitting at the time, in the chair of the Under Secretary of State for Arms Control and International Security, I never saw any evidence of any effort at the State Department to prevent inquiry into the lab-leak idea. To the contraryâas you can now see proven by documents in the public recordâI supported looking into the lab-leak hypothesis. I cared so much about getting to the truth about WIV, in fact, that I insisted that we do the work in a way that could stand up to scrutiny. (If youâre serious about something being done, you have an obligation to ensure itâs done right. Wanting less than that just makes you a hack.) And I am aware of no one anywhere in the Department who thought that the laboratory hypothesis should be ignored or ruled out.
So there was no conspiracy to quash inquiry into the lab-leak question, at least not at the State Department. But there was a demand for intellectual rigor and analytically defensible conclusions in doing that important inquiry. For making that demand, however, I make no apologies. I was doing my duty.
What happened after that? Well, one might infer that my State Department superiors in fact agreed with the account in my January 8th message of the weaknesses that AVCâs expert panel had pointed out in the supposed âstatisticalâ proof that SARS-CoV-2 had to be the result of human intervention. Neither Secretary Pompeo nor any other serving US official, after all, adopted and voiced the scientific assertions about WIV origin that AVC had previously been briefing to interagency stakeholders. Instead, Secretary Pompeo issued a âFact Sheetâ on January 15th that accurately recounted downgraded intelligence reporting we had received that seemed relevant to the question of whether SARS-CoV-2 had originated at the laboratory.
My superiors at the Department were not shy people, and I have no doubt that had they felt AVCâs scientific assertions could pass muster with real scientists, they absolutely would have made this case in public, and loudly. They chose not to do so, however. I suspect that we should read into this their quiet endorsement of my conclusion that AVCâs scientific case wasnât ready for prime time. (Perhaps someone can ask my former bosses what precisely they thought of the merit of AVCâs âstatisticalâ argument about genomic variation, and whyâif it was indeed good scienceâthey seem to have dropped those assertions. I can tell you only one thing about this with certainty: not pursuing AVCâs âscientificâ argument after the January 7th panel meeting wasnât my decision. By the end of the day on January 8th, after sending my message of caution, I had left the Department. It would be interesting to know what discussions happened thereafter.)
But I do think that what happened next is important. Instead of focusing on purported âscientific proofsâ of laboratory origin, public discussion of the COVID-origins issue thereafter shifted to the questions and suspicions that had been raised about WIV by our intelligence information, as outlined in Secretary Pompeoâs âFact Sheet.â This was, in my view, much the better way to go. Before leaving the Department, in fact, I had myself reviewed and cleared an early draft of that âFact Sheetâ as the downgraded information started to go around for interagency clearance, and I was glad to see it later emerge publicly on January 15th. Tellingly, the Biden Administration has not questioned that information, and a robust debate is now underway about possible laboratory origin.
But let me be frank. Anyone who cares about ensuring that the lab-leak hypothesis is taken seriously should probably be thanking me, rather than vilifying me. I suspect that my push for scientific vetting of AVCâs assertions actually helped save the lab-leak hypothesis from being preemptively discredited. The fact that we finally now have a credible public debate on the question owes much to the fact that pursuing these issues wasnât tainted by the State Department signing the US Governmentâs name to scientific assertions that we already knew hadnât stood up well to scrutiny.
Iâve been around the arms control and international security business for quite a while now, including spending 2003â06 as Principal Deputy Assistant Secretary in what is now the AVC Bureau. As I told someone the other dayâan old and dear friend and former colleague who has now started demonizing me on the basis of the lies being spread about these issuesâhonesty, accuracy, and intellectual integrity are the strongest weapons that an arms control verifier has. These things need to be safeguarded carefully, for they are priceless. They are what separates the truth-teller from the ideological crank.
I am heartsick at the ugliness of the campaign against me in the press today, but I remain proud of my role in insisting upon fidelity to these values at a time when some officials seemed to be slipping. I dearly hope that we can all now put fratricidal distractions aside and get back to the real task: figuring out what the hell happened in Wuhan.
Conclusion
The actual details of all this State Department infighting are, Iâll admit, somewhat boring. They certainly donât map satisfyingly onto a moralistic narrative of redoubtable heroes fighting for right against malevolent cabals and institutional corruption. Nor are they well suited for spinning up rants of performative outrage by the occasional pundit disinclined to let little things like âtruthâ get in the way of the good Nielsen ratings that come from spinning a sexy narrative of deceit and conspiracy.
Nevertheless, these demonstrable facts about the positions I took at the time are clear in the record. If thatâs not important to you, youâre reading the wrong essay, and I apologize for wasting your time. If youâve read this far, however, my guess is that facts are indeed important to you. So thanks for listening.
