And yes, I agree, that was the straw. Trump would have put up with Megyn and even the planned ambush by the muslim and the Mexican. The stupid press release gives him plausible justification to make a command decision. Bam - he demonstrates leadership.
I think they would have set him up to make him look foolish on stage to the point of walking off the stage... Here he controls the outcome. If it costs him vote fine. Don’t know why he’s meeting with O’Reilly other than to give O’Reilly the chance to tell him he’s wrong.
I would turn the interview around. Ask O’Reilly if he thought the press release and having plants there proper? Ask him if he honestly considered it to be a true debate.
