President Donald Trump claimed Monday that pardons recently issued by Joe Biden to lawmakers and staff on the congressional committee that investigated the Jan. 6, 2021, Capitol riot have no force because the-then president signed them with an autopen instead of by his own hand.

The president has recently made baseless claims that Joe Biden routinely used an autopen and that his unelected aides used the executive power of the presidency without his knowledge.

President Donald Trump raised eyebrows Monday by claiming that pardons issued by President Joe Biden are “invalid” because they were signed using an autopen, an electronic device that replicates a person’s signature.
