This is a bullshit fake news story. If Trump offered the money, he would deliver on it. Many times in the past he has given people money with no publicity expected! For instance, when that marine was trapped in Mexico for a year over a wrong turn and they locked him up and tormented him, and Obama did nothing, when he finally got released, Trump gave him a big check to help him get his life back on track. Another time, Trump read about a guy on a bridge looking to commit suicide and some guy driving a bus saw him, stopped and talked him in. Trump heard about it and found the guy and called him a hero and gave him a reward.
All this crap you keep hearing about Trump is 90-95% BULLSHIT put out there to try to fracture his base and get his supporters to lose faith in the guy. The Dems have no chance of beating the guy in a straight-up contest, the only way they ran Hillary was with a million lies and cheats (and they still lost), and they know he'll win again (who the hell does the Dems have to run against him?) unless they can get in the heads of his voters.
