Why Fauci's use of the Fifth draws GOP criticism despite Trump invoking it 440 times

WASHINGTON, DC: Former National Institute of Allergy and Infectious Diseases (NIAID) director Dr Anthony Fauci's decision to invoke the Fifth Amendment 111 times during a Republican-led Senate hearing on Wednesday, July 29, has reignited debate over the legal limits of presidential pardons, congressional oversight and constitutional protections.

Fauci declined to answer questions about the COVID-19 pandemic after receiving legal advice from his attorneys, while Republican senators argued his 2025 pardon from former President Joe Biden eliminated his basis for remaining silent. The dispute has also drawn comparisons to President Donald Trump's decision to invoke the Fifth Amendment more than 440 times during a 2022 civil deposition. 

Why did Anthony Fauci invoke the Fifth despite receiving Joe Biden's pardon?

Fauci opened the hearing by accusing Senate Homeland Security Committee Chairman Rand Paul of pursuing a politically motivated effort to prosecute him, saying the senator was attempting to get him to say "something, anything" that could place him "behind bars."

Acting on the advice of counsel, Fauci invoked his Fifth Amendment right against self-incrimination 111 times rather than answer questions on COVID-19 origins, gain-of-function research, federal record-keeping and other issues. The Fifth Amendment protects individuals from being compelled to provide testimony that could incriminate them in criminal proceedings. 

Although Biden granted Fauci a sweeping federal pardon last year covering offenses dating from 2014 to 2025, legal experts note that a pardon does not extend to future conduct. False statements made under oath after the pardon, if proven, could still expose a witness to potential perjury charges.

Republicans disputed Fauci's reliance on the Fifth Amendment. Paul argued that because the pardon eliminated potential criminal exposure for the conduct under investigation, Fauci no longer faced self-incrimination for those matters.

"My question was limited to the period of your pardon only," Paul said. "I find your objection unsupported and direct you to answer the question," Fauci again invoked the right.

Paul later announced that the Senate Homeland Security Committee intends to begin contempt proceedings against Fauci. A contempt citation does not automatically result in criminal penalties but could be referred to the DOJ or pursued through other congressional enforcement mechanisms.

Why are Republicans comparing Anthony Fauci's testimony with Donald Trump's Fifth Amendment use?

Several Republican senators used the hearing to criticize Fauci's repeated refusal to answer questions.

Senator Josh Hawley mocked Fauci by asking a series of basic questions, including the day of the week, the color of his tie and the color of the carpet. Fauci invoked the Fifth Amendment each time, prompting Hawley to remark, "Nothing says honesty like taking the Fifth, huh, doc?"

The hearing has also drawn comparisons to Trump's own invocation of the Fifth Amendment during a 2022 civil deposition in New York.

Trump declined to answer questions more than 440 times, later saying he believed he and his family were the targets of what he described as an "unfounded, politically motivated Witch Hunt." Like Fauci, Trump argued that invoking the Fifth Amendment was appropriate under the advice of counsel when facing legal scrutiny he viewed as politically motivated.
