President Trump claims some of former President Biden's pardons he gave at the end of his presidential term are void because they were done by autopen. Autopen is a device that signs a president's signature on documents without them needing to handwrite it themselves. This tool has been used by past presidents. NewsNation political and economic contributor Mick Mulvaney and NewsNation legal contributor Jesse Weber join "The Hill" to discuss why Trump is raising the issue of Biden's use of the autopen. #DonaldTrump #autopen #JoeBiden "The Hill on NewsNation" combines the power of two trusted news sources to define today's most-pressing issues, and question Washington's power brokers on what matters most to the people they serve and what matters most to Americans.
