President Donald Trump claimed late Sunday that all of former President Joe Biden’s last-minute pardons were signed using an autopen, the New York Post reported.

An autopen is a machine that replicates a handwritten signature, often used by politicians, executives, and celebrities to sign large volumes of documents.

In a post to Truth Social, Trump said, “In other words, Joe Biden did not sign them but, more importantly, he did now anything about them!”

Trump alleged without providing evidence that Biden was not aware of or did not approve the pardoning documents.

He also warned that members of the former House Jan. 6 select committee who received pardons from Biden would be “subject to investigation at the highest level.”

“Therefore, those on the Unselect Committee, who destroyed and deleted ALL evidence obtained during their two year Witch Hunt of me, and many other innocent people, should fully understand that they are subject to investigation at the highest level,” Trump wrote.

“The fact is, they were probably responsible for the Documents that were signed on their behalf without the knowledge or consent of the Worst President in the History of our Country, Crooked Joe Biden!”

Biden preemptively pardoned all nine members of the Jan. 6 Committee, including its two leaders—Rep. Bennie Thompson, D-Miss., and then-Rep. Liz Cheney, R-Wyo., who later pledged to vote for then-Vice President Kamala Harris in the 2025 election.

On his last day in office, Biden issued a series of 11th-hour pardons, including preemptive ones.
