Q: Story highlights Donald Trump dumps the Republican loyalty pledge as race heats up 
  
 He says he's "been treated very unfairly" by the Republican National Committee 
  
 (CNN) Donald Trump, Ted Cruz and John Kasich all stepped back from their earlier pledge to support the eventual Republican nominee during Tuesday night's CNN town hall. 
  
 "All of us shouldn't even have answered that question," Kasich said of the pledge party officials asked all the candidates to sign in September. 
  
 "No, I don't anymore," Trump said, when asked by CNN's Anderson Cooper if he continued "to pledge to support whoever the Republican nominee is?" 
  
 Trump said he has "been treated very unfairly" by the Republican National Committee and party establishment figures. The billionaire front-runner accused rival Cruz of "essentially saying the same thing" in response to a question about the pledge. 
  
 Earlier, Cruz had told Cooper when asked the same question: "I'm not in the habit of supporting someone who attacks my wife and my family ... I think nominating Donald Trump would be an absolute trainwreck, I think it would hand the general election to Hillary Clinton."

 “No, I don’t anymore,” Trump replied, when asked at a CNN town hall event whether he still supported a pledge he made last year to support whoever is the Republican nominee for the Nov. 8 election. 
  
 Trump’s signing of a loyalty pledge last September was important in helping him gain credibility within the Republican National Committee. The pledge was also signed by all his rivals for the presidential nomination. 
  
 His aboutface came as he tries to fend off a challenge from Cruz, a U.S. senator from Texas who is running second to the New York billionaire in the race for the 1,237 delegates needed to win the nomination. 
  
 Trump and Cruz were enmeshed in a fight last week involving their wives, with a Cruz SuperPAC publishing a provocative photo of Trump’s former model wife, Melania, and Trump retaliating by tweeting an unflattering photo of Cruz’s wife, Heidi. 
  
 Cruz, asked earlier at the CNN town hall whether he also would honor the pledge to support the nominee if it was not himself, declined to give a straight answer. 
  
 “Let me tell you my solution to that,” Cruz said. “Donald is not going to be the GOP nominee. We’re going to beat him.” 
  
 GOP is the acronym for Grand Old Party, a nickname for the Republican Party. 
  
 Trump said he could do without Cruz’s support. 
  
 “I watched him tonight and I watched how tormented he was when you asked him that question,” Trump told CNN moderator Anderson Cooper. “I don’t want to have him be tormented. Let me just tell you I don’t want his support, I don’t need his support. I don’t want him to be uncomfortable.” 
  
 Trump also said he recognized that several of those who have dropped out of the race might harbor ill feelings towards him, mentioning former Florida Governor Jeb Bush, Wisconsin Governor Scott Walker and U.S. Senator Rand Paul of Kentucky. 
  
 Walker endorsed Cruz earlier on Tuesday, with Wisconsin’s primary vote coming up on April 5. 
  
 “I drove him out of the race,” Trump said of Walker, who abandoned his presidential bid last autumn. “I drove Jeb Bush out of the race, I drove Rand Paul out of the race. I understand why they don’t like me.” 
  
 A third Republican presidential candidate, Ohio Governor John Kasich, was also tentative about honoring the pledge. He told the town hall he had been “disturbed by some of the things I’ve seen” during the campaign, adding, “I want to see how this finishes out.” |||||
A:
This election season has delivered yet another oddity: a CNN town hall event featuring three Republicans who won't commit to supporting the Republican nominee. Donald Trump was the most direct when asked by Anderson Cooper whether he was sticking to his pledge "to support whoever the Republican nominee is." "No, I don't anymore," Trump said. It was harder for Cooper to get a straight answer out of Ted Cruz, reports Reuters, though he eventually said he is "not in the habit of supporting someone who attacks my wife and attacks my family." Trump "is not going to be the GOP nominee," Cruz said. "We're going to beat him." John Kasich also wouldn't commit to honoring the pledge. He said he was "disturbed" by some of what he's seen on the campaign trail and that the GOP candidates "shouldn't even have answered that question" last year when they were asked to rule out third-party bids. "I have to think about what my word and endorsement would mean," he said. "[I've] got to see what happens." Trump didn't seem perturbed by the prospect of not getting Cruz's vote. He "doesn't need to support me, I have tremendous support right now from the people," Trump told Cooper. "I don't really want him to do something he's not comfortable with."
