Donald Trump spent his first session back in the Oval Office signing executive orders to pardon all January 6 defendants and declare dangerous Mexican drug cartels as 'terrorists' while finding a letter written to him by Joe Biden.

Trump said he was pardoning about 1,500 defendants and issuing six commutations. He also directed the attorney general to seek dismissal of about 450 pending criminal cases against Jan. 6 defendants.

The pardons fulfill Trump's promise to release supporters who tried to help him overturn his election defeat four years ago.
