We know Trump personally threatened Republican congressmen who refused to vote for Trumpcare, but you don't have to take my word for it. Members of the Freedom Caucus and the moderate Tuesday Group told reporters that he threatened them, but you don't have to take their word for it either. Trump himself threatened specific members of Congress in a series of public tweets last week.
With all of that said, Trump told the Financial Times that he never wanted them to hold a vote.
"You know that we didn’t take a vote," Trump said in an interview with the Financial Times. "I didn’t want to take a vote. It was my idea. I said why should I take a vote." [...]
"Yeah, I don’t lose. I don’t like to lose," Trump told the Financial Times. "But that wasn’t a definitive day. They are negotiating as we speak. I don’t know if you know. They are negotiating right now. There was no reason to take a vote."
This is really the perfect lie for Trump to tell because his own supporters attacked members of Congress and Speaker Paul Ryan for not holding a vote, but Trump says he didn't actually want them to vote.
Pretty much everyone comes out looking a horse's ass when they work with Trump. He regularly gaslights his own supporters who may not even be sure what positions of his they should defend lest he change his story the following day or even the following hour.
Trump may not "like to lose," but he has lost quite a bit since taking office. His Muslim ban has been blocked so many times in so many different courts I actually lost count.
It occurs to me that by back-tracking on his threats, Trump has ensured that his next round of threats will be ignored.
