President Donald Trump took another jab at his predecessor and his use of the presidential autopen on Monday.

“Joe Biden would use the autopen,” Trump said in a video shared by the White House’s Rapid Response account on X. “He’d have an autopen follow him. You know Joe Biden? He didn’t sign — he was incapable of signing his name, so they’d follow him around with this big machine. You know what it was called? An autopen.”
