Trump has lots to apologize for.  let me just list a couple:

1.  He has refused to release his tax returns even though all presidential candidates since Nixon has.  He promised that he would release them, then changed his mind.  This makes him a big fat liar.

2.  He promised health care second to none but instead backed a plan that was just plain crap.  Liar liar pants on fire....

3.  He promised that he would drain the swamp but instead has made it twice as big and 10 times as deep.  Already it is almost filled up with slime.  Way to drain the swamp Donald.
