Republican lawmakers have dubbed the revelation a "constitutional scandal" and called for the investigation of thousands of documents signed by Biden during his tenure. President Donald Trump admitted to using an autopen days after attacking former president Joe Biden of doing the same to issue a series of pardons.

Former President Joe Biden, in an interview with the New York Times, said that he personally made every clemency and pardon decision during the end of his presidency.

Trump said that the autopen use is "one of the biggest scandals" in "50 to 100 years" because Biden "knew nothing about what he was signing."
