The Autopen, the Presidency and the Constitution: What to Know

Machines to copy signatures have been used by presidents since Jefferson. In 2005, the government held that presidents may use them to sign official documents.

WASHINGTON—The “autopen” is in vogue. On March 17, President Donald Trump announced in a late-night social media post that he would ignore several pardons issued by his predecessor, President Joe Biden, because they were allegedly signed by autopen.

An autopen is a machine that reproduces handwriting. In the case of elected officials, who are expected to sign thousands of official documents on a regular basis, autopens are often used to reproduce their signatures in lieu of them signing each paper by their own hand.
