WASHINGTON — Joe Biden on Monday wrapped up a more than 50-year political career, but promised that “we're not leaving the fight,” as he bid farewell to the presidency and flew to California to unwind with his family and ease back into private life.

President Biden wrote President-elect Donald Trump a letter as he departed the White House, keeping to tradition. As Biden awaited Trump’s arrival at the White House, he was asked if he wrote a letter to Trump.

President Trump discovered his traditional letter from President Biden on Monday evening with reporters in the Oval Office and commented that it sets a "bad precedent" for Biden to pardon members of his family on his way out of office.
