Donald Trump has declared he intends to cancel most of the executive orders signed by Joe Biden, his predecessor as president of the United States.

In a post on social media, Trump claimed baselessly that Biden had not signed off on the orders himself, saying that “the radical left lunatics circling Biden around the beautiful Resolute Desk in the Oval Office took the Presidency away from him” by signing his name using an autopen – a signature machine that has commonly been used by US presidents since the device’s invention.

“The Autopen is not allowed to be used if approval is not specifically given by the President of the United States,” Trump said, baselessly alleging that it was operated by other people without Biden’s approval and claiming that “approximately 92%” of all executive orders were therefore invalid.
