Donald Trump has asserted that presidential pardons issued by Joe Biden are invalid due to their execution using an autopen machine. In posts on his social media platform, Trump referred to the January 6 committee as the “Unselect Committee of Political Thugs” and claimed that a lack of Biden’s personal signature and oversight invalidates the pardons. No evidence has been provided for this claim. The Heritage Foundation’s report speculated about Biden’s use of an autopen for signature reproduction. Legal precedents suggest that a president’s decision method for pardons is at their discretion and can be executed beyond personal signatures. Trump also expressed this view on Air Force One, before granting pardons to the members of the House January 6 committee investigating the Capitol attack he inspired. This action amplified his disapproval of the investigation, suggesting unaware approval and potential criminal action for those involved in procuring the pardons without Biden’s knowledge. Trump further accused the committee of destroying evidence, promoting unsubstantiated right-wing claims.
