Texas Sen. Ted Cruz put on a "classless" display when he refused to endorse Republican presidential nominee Donald Trump, the businessman's son said.
Cruz withheld his endorsement and, to cap off a half-hour speech, told the crowd at the Republican National Convention to vote their consciences instead of asking them to vote for Trump. The speech drew jeers and ended with Cruz being booed off the stage.
"I think the people in this arena spoke for themselves," the younger Trump told CBS News. "I thought it was classless, to tell you the truth. I thought it was a little bit classless."
As it was becoming clear that Cruz would withhold his endorsement, members of the crowd began chanting "We want Trump!" and turned away from the Texas senator as Trump entered the arena.
Cruz was heckled by delegates after his speech, and was turned away from a suite occupied by a major GOP donor, according to CNN.
On July 21, he defended his speech, saying he withheld his endorsement because of Trump's attacks on his family.
"I am not in the habit of supporting people who attack my wife and attack my father," Cruz said.
That didn't stop major GOP figures from criticizing Cruz and questioning his loyalties. New Jersey Gov. Chris Christie called Cruz "selfish," while Trump attorney Michael Cohen said the speech was "political suicide," CNN reported.
"He signed a pledge at the beginning of this process," Eric Trump said. "When he didn't do the right thing people went crazy ... I've never seen boos like that, I never heard boos like that. The house, the whole auditorium was literally shaking with boos. I mean, how do you get booed out of your own convention? It was unbelievable."
