Legal experts said the Constitution doesn’t require presidents to directly sign pardons, and that Trump can't unilaterally reverse them.

President Donald Trump has repeatedly said former President Joe Biden signed pardons with an autopen, a mechanical device that uses a robotic arm with an attached pen. When Trump installed portraits of past presidents in the White House, a photograph of an autopen took the place of Biden’s portrait.

President Donald Trump said all "Documents, Proclamations, Executive Orders, Memorandums, or Contracts" signed by former President Biden's autopen are "void," including pardons and commutations.

Legal scholars reject Trump’s argument that autopen pardons can be undone, saying constitutional clemency power remains final.

A majority now believe the Constitution should be amended to limit this power, with even Republicans divided on Trump's nearly 1,600 pardons this year.

President Trump’s use of his clemency power is drawing criticism as he grants pardons and commutations that at times appear to contradict his agenda and focus largely on people charged or

The autopen is a device that reproduces a person’s signature with precision, often used for high-volume or ceremonial documents.

U.S. President Donald Trump said on Tuesday he is terminating all documents, including pardons, that he said his predecessor Joe Biden had signed using an autopen, a move that legal experts doubted would hold up in court.

The Constitution grants Pres. Trump the power to pardon, and he can pardon for a good reason, a bad reason or no reason at all.
