He has been a traitor to America for a very long time. He was turned while at the Hanoi Hilton and has been a Communist plant and has subverted and stole from the American People since he returned.
Since his days are numbered, he has pulled out all stops (his voting and actions abroad show this) to do as much harm before he passes. His handlers have cut him loose to do as much damage as possible because they know the noose is tightening with President Trump in charge.
People call him a hero. I just call him a traitor and a waste of space.
Because he IS a traitor! The North Vietnamese didn't give him the sobriquet 'Songbird' for nothing!
