Why Anthony Fauci might not be safe after pleading the Fifth

(CNN) — By now in American politics, we’ve become accustomed to high-profile figures pleading the Fifth to avoid answering questions they believe could be used to incriminate them. That includes President Donald Trump doing it more than 400 times in a civil case in 2022.

But when it comes to Dr. Anthony Fauci invoking the Fifth Amendment — as he did repeatedly in Senate testimony Wednesday — it’s much more complicated.

That’s because Fauci was pardoned last year by then-President Joe Biden.

Indeed, Wednesday’s hearing is very unlikely to be the end of the story. And it could actually grease the skids for Republicans and the Trump administration to do something many of them have openly floated: Trying to put Fauci in prison.

They’re ostensibly not trying to prosecute Fauci for what he did during the Covid pandemic, but have talked about holding him in contempt of Congress — a threat to initiate a process that would result in the Justice Department considering whether to charge him.

GOP efforts to prosecute Fauci formed the basis of his refusal to answer questions Wednesday. Specifically, he cited Senate Homeland Security and Governmental Affairs Chair Rand Paul’s years-long attacks against him.

Fauci claimed the Kentucky Republican was trying to “get me to say something, anything, that could vindicate his repeated public pledges that I end up, in his words, ‘behind bars.’”

But the key difference between Fauci pleading the Fifth and others doing so is that Fauci was pardoned by Biden in early 2025.

On his way out of office, Biden issued preemptive pardons for Fauci and others targeted by incoming President Trump while citing signs the new administration and its allies might try to drum up prosecutions against them. (That fear that has been legitimized, given the Trump Justice Department’s efforts to target Trump foes based on often flimsy evidence.)

And Fauci, the former director of the National Institute of Allergy and Infectious Diseases, was not only pardoned; he received a very broad pardon that covered virtually anything related to his government service between January 2014 and January 2025.

In other words, Fauci is already immune from prosecution for many of the potential alleged crimes Paul and the committee’s Republicans could try to link him to from the Covid era.

But Fauci indicated he was pleading the Fifth because he feared Republicans would try to lay a perjury trap — i.e. try to get him to say something that could be used to bring a perjury case against him.

Indeed, some prominent figures had spoken before the hearing about Fauci possibly still being prosecuted for perjury, despite his pardon. They included Health and Human Services Secretary Robert F. Kennedy, Jr. and conservative lawyer John Yoo, who both suggested as much in interviews on Fox News.

(While Fauci’s medical advice during the Covid pandemic has been roundly criticized by Republicans, there is little to link him to criminal activity. And polling earlier this year showed a majority of Americans still had confidence in him.)

But whether it’s enough for Fauci to plead the Fifth and be done with it is a major unanswered question.

There is a tension between Fifth Amendment protections and Congress’ investigative authority. And witnesses who claim they are protected from answering questions can be called upon to justify that in court and can be held in contempt.

Former Trump adviser Steve Bannon, for instance, invoked executive privilege to avoid testifying about efforts to overturn the 2020 election. He was later convicted of contempt of Congress and sentenced to four months in prison when the courts rejected his claim. (The Trump DOJ has since sought to dismiss his conviction.)

Paul signaled Wednesday that he was scheduling a contempt vote for Fauci in his committee for next week, saying, “It’s against the law to obstruct an investigation of Congress. There will be repercussions for your refusal to testify.”

It’s worth noting that even if the panel votes to hold him in contempt, an actual referral to the Justice Department requires a majority of the full Senate, and that vote would have to clear a filibuster. That means Paul would need a handful of Democrats to get on board to follow through — or convince someone to take up the cause in the House, where it only requires a simple majority.

While there’s a long way to go before Fauci potential charges, some legal experts say his claim to the Fifth Amendment here could be dicey.

“Whether that concern (about prosecution) is sufficient to support a Fifth Amendment invocation would ultimately be for a court to decide,” said former federal prosecutor Danya Perry.

She added: “Fauci would point to Paul’s repeated accusations and threats as evidence that the prospect of prosecution was concrete rather than speculative, even if he believed any such prosecution would ultimately fail.”

Mark Osler, a law professor at the University of St. Thomas, wrote in an email that “the pardon would seem to cover Fauci’s previous congressional testimony prior to January 19, 2025. Thus, he can’t assert the 5th based on the fact that he may be asked questions that reveal his prior testimony as false (or at least subject to such a charge).”

But Osler said Fauci could argue his pardon has some holes that could be exploited — such as conduct that occurred before 2014 or that didn’t relate to his government service.

CNN senior legal analyst Elie Honig wagered that Fauci would have a strong claim not just because of the time limit of the pardon, but also because he could fear being prosecuted for potential state crimes, which aren’t covered by a federal pardon.

“He certainly can take the Fifth if he has exposure outside of the pardon, which he certainly does,” Honig argued on CNN.

If courts found that Fifth Amendment protections didn’t apply to Fauci’s testimony, he could conceivably agree to testify at that point and avoid possible contempt charges. But he would have to balance that against whatever potential prosecution he might fear his testimony could lead to.

Interestingly, this is a scenario that was often previewed during and shortly after Trump’s first term, but with the roles somewhat reversed.

Back then, the thought was that Trump could pardon his allies, but that meant it could potentially be easier to make them testify against him.

Now some Republicans are girding to continue the fight with Fauci.

“Let’s just get one thing straight: You don’t have any rights under the Fifth Amendment, because you’ve been pardoned, as you very well know, as the Supreme Court has been clear for a century and more,” GOP Sen. Josh Hawley of Missouri said at Wednesday’s hearing.

Hawley went on to cite Fauci’s lawyers, one of whom was escorted out of the hearing at Paul’s request after a tense back-and-forth.

“Your lawyers sitting behind you, now shifting nervously in their chairs — they know it,” Hawley said. “This isn’t about the Constitution. This isn’t about the law. This is about contempt — contempt for this body and contempt for the American people.”

La IA crea 16 virus desde cero, lo que combatiría la resistencia a antibióticos, pero alerta sobre su posible uso indebido

Científicos utilizaron un programa de inteligencia artificial para crear genomas virales diferentes de los de cualquier virus conocido en la naturaleza y capaces de atacar huéspedes específicos, según un nuevo estudio. El avance resulta prometedor para la medicina, pero también suscita preocupación por su posible uso indebido.El estudio, publicado el jueves en la revista Science, señala que las secuencias genéticas procedentes de millones de fuentes “de todos los dominios de la vida” sirvieron como corpus de entrenamiento para Evo, una herramienta de IA. El proceso es similar al entrenamiento de ChatGPT y otros modelos de lenguaje con grandes cantidades de textos existentes.Los científicos de Stanford University y el Arc Institute utilizaron después la IA para generar miles de combinaciones genómicas dentro de un marco específico: debían ser compatibles con células de la bacteria E. coli. De los miles de genomas generados por la IA, los investigadores sintetizaron y probaron unos 300 en el laboratorio y determinaron que 16 correspondían a virus viables.Los nuevos virus son bacteriófagos, es decir, virus que infectan bacterias, pero no a los seres humanos.De acuerdo con la investigación, el corpus genético ayudó a la IA a “aprender las restricciones evolutivas” de los genomas naturales. Sin embargo, los científicos descubrieron que uno de los nuevos virus contenía un elemento “evolutivamente distante”. Esto indica que la IA produjo cambios cuya viabilidad podría haber tardado millones de años en manifestarse mediante la evolución natural.Las pruebas mostraron que una combinación de los nuevos virus podía vencer la resistencia a los antibióticos en algunas cepas de E. coli, algo que no consiguió una “combinación comparable de fagos obtenidos de fuentes naturales”.Esto “abre una vía para generar terapias adaptables y robustas con fagos contra patógenos que evolucionan rápidamente”, escribieron los autores.Se trata de un hito científico importante, en momentos en que los investigadores buscan combatir la creciente resistencia a los medicamentos en microorganismos como E. coli.“El avance logrado es significativo”, dijo Jordi García Ojalvo, profesor de biología de sistemas de la Universidad Pompeu Fabra de Barcelona, en declaraciones al Science Media Centre.No obstante, el avance también suscita reservas.“Aunque esto resulta prometedor para las aplicaciones en las ciencias de la vida, también plantea interrogantes urgentes sobre seguridad y protección biológicas”, escribieron especialistas del Johns Hopkins Center for Health Security en un artículo complementario publicado en Science.“Ya existe la capacidad de crear genomas virales mediante IA generativa; lo que no existe es la gobernanza necesaria para utilizarla de manera segura”, escribieron.Los investigadores abordaron directamente las consideraciones de seguridad y protección biológicas en su trabajo. Los especialistas de Johns Hopkins señalaron que lo hicieron “de manera más deliberada que la mayoría de los desarrolladores de potentes modelos biológicos de IA”.La nueva investigación se centró en la bacteria E. coli y en un tipo de virus que no puede infectar a los seres humanos. No está claro hasta qué punto el método podría aplicarse a otros virus.Los autores del artículo complementario señalaron un campo particularmente peligroso que, a su juicio, no debe explorarse: los patógenos capaces de infectar células u organismos eucariotas. Estos pueden causar diversas enfermedades en los seres humanos, entre ellas la malaria y ciertas infecciones por levaduras.“Esos genomas podrían codificar nuevos patógenos capaces de infectar a seres humanos, animales o plantas de formas que las medidas existentes quizá no puedan contener”, escribieron.García Ojalvo dijo que el riesgo de bioseguridad que plantea la nueva investigación es menor que el de otras herramientas de IA. Esto se debe principalmente a que cada genoma debe probarse por separado después de su diseño y a que la tasa de éxito es baja: solo 16 virus resultaron viables entre los cientos de miles generados.“Es difícil imaginar que estos modelos generen automáticamente genomas viables de manera inmediata”, dijo.The-CNN-Wire™ & © 2026 Cable News Network, Inc., a Warner Bros.
