The president has said the previous administration used the device to sign executive orders and pardons that President Joe Biden wasn’t aware of — a claim Biden vigorously denies.

ToplinePresident Donald Trump on Wednesday ordered Attorney General Pam Bondi to investigate former President Joe Biden’s actions during his term, alleging his staff covered up the former president’s “cognitive decline” and questioning his use of an “autopen” to sign certain orders.

The Justice Department under Democratic and Republican administrations has recognized the use of an autopen to sign legislation and issue pardons for decades. Trump presented no evidence that Biden was unaware of the actions taken in his name, and the president’s absolute pardon power is enshrined in the U.S. Constitution.
