Then there was that guy at his sentencing recently who apologized to the family for getting drunk and killing their child with his car.  Apologies are fine, but the facts still remain.  The only reason Gianforte apologized is because he was ordered to by Paul Ryan, purely for political reasons.
I'm not convinced that Trump is the cause of this one.  This guy believes that the Earth is 10,000 years old and dinosaurs rode on the arc.  He's a feeble-mined lackey of the evangelical cult.  He didn't need Trump to unhinge him. He came that way.
