President Donald Trump has claimed that the thousands of pardons signed during the Biden administration are void, due to alleged autopen usage.

On Biden’s final day as president, January 19, he met with his advisors until almost 10 p.m. to discuss different preemptive pardons, according to the Times. According to emails acquired by the Times, at 10:03 p.m., an aide gave Zient’s assistant a summary draft of the official decisions made at the meeting.

Former President Joe Biden orally granted thousands of pardons and commutations in the final months of his term, he told the New York Times.
