Donald Trump's name hasn't been too popular in Springfield, Illinois this past week Abe Lincoln's hometown has been hosted the Vietnam Veterans of America National Convention.
Former POW William Robinson spent seven a half years in captivity. He believes Trump said POW turned Arizona Senator John McCain was not a hero, for political gain. He believes Trump's move exploits Vietnam veterans.
Trump's claim doesn't sit well with Robinson.
Robinson was held for seven and a half years starting in 1965. That was longer than any other enlisted man.
