The Justice Department posted pardons online bearing identical copies of Donald Trump’s signature before quietly correcting them this week after what the agency called a “technical error.”

The replacements came after online commenters seized on striking similarities in the president’s signature across a series of pardons dated Nov. 7, including those granted to former New York Mets player Darryl Strawberry, former Tennessee House speaker Glen Casada and former New York police sergeant Michael McMahon.

In fact, the signatures on several pardons initially uploaded to the Justice Department’s website were identical, two forensic document experts confirmed to The Associated Press.
