Legal clash over Fauci's Fifth Amendment claim after Biden's sweeping pardon

In a contentious Senate hearing, Dr. Anthony Fauci invoked the Fifth Amendment over a hundred times, despite receiving a full and unconditional presidential pardon from former President Joe Biden in early 2025. Republican committee chair Rand Paul argues the pardon removes any realistic chance of federal prosecution for Fauci’s pre-2025 actions, making the privilege untenable, and will move to hold him in contempt of Congress.

Fauci’s attorneys counter that the pardon does not shield him from potential perjury liability arising from his testimony or from state-level criminal probes, which remain unaffected by a federal pardon. The legal debate draws on 19th-century Supreme Court decisions that a pardoned witness loses the Fifth Amendment shield for covered offenses, while also considering later rulings that a pardon must be accepted and does not protect future wrongdoing.

Scholars highlight the scarcity of case law on how a sweeping pardon interacts with congressional oversight. The committee’s contempt resolution could trigger Department of Justice action and eventual judicial review of the constitutional questions involved.
