The House Oversight and Accountability Committee says it is assembling evidence that could be used to challenge the legality of several pardons and executive orders issued by former President Joe Biden. Chairman James Comer told reporters on Aug. 10 that the panel’s investigation has uncovered material raising “serious questions” about whether Biden personally approved the documents in the final months of his administration. Comer cites Biden’s extensive reliance on an autopen and longstanding concerns over the 82-year-old Democrat’s mental acuity—heightened after his faltering 2024 debate performance and withdrawal from the presidential race—as grounds for doubting that the former president was aware of what he was signing. The committee has subpoenaed White House aides and Biden’s former physician; several witnesses have invoked the Fifth Amendment, according to Comer. Among the clemency actions under scrutiny are Biden’s pardons of infectious-disease expert Anthony Fauci, former Joint Chiefs Chairman Mark Milley and Representative Adam Schiff. President Donald Trump has endorsed the committee’s effort, saying the findings could render the pardons and related executive orders "null and void." Legal analysts expect any attempt to rescind Biden’s actions to prompt a court fight. Former Harvard Law professor Alan Dershowitz has argued that questions over autopen signatures and presidential intent would almost certainly reach the Supreme Court, making the committee’s evidence critical to any future litigation.
