Who Cares!? But the disrespect on Trump's part jus show how much of a loser he is. I had to look up the last time a sitting President didn't show up to his successors inauguration and this is what I found. 'Only three incumbent presidents have refused to accompany the president-elect: John Adams, John Quincy Adams, and Andrew Johnson. Around or after 12 noon, the president takes the oath of office, usually administered by the chief justice of the United States, and then delivers the inaugural address.' So this would make Trump the 4th President. SMH. I still can't believe the President of The United States was Donald Trump.
