Heckled Ted Cruz Defends Decision Not to Endorse Trump: I Don't Support People Who Attack My Wife

The feud between Cruz and Trump doesn't look like it will end anytime soon.

Ted Cruz is standing by his decision not to endorse Donald Trump during his RNC speech Wednesday night.

"I am not in the habit of supporting people who attack my wife and attack my father," Cruz told members of the Texas delegation Thursday morning in Cleveland, CNN reported.

While battling Cruz for the GOP nomination on the campaign trail earlier this year, Trump went on the offensive, bringing up his Republican rival's wife and father with bold claims and threats.

The billionaire said he planned to expose purported secrets about Heidi Cruz, who had reportedly suffered from depression. He also endorsed a National Enquirer article that claimed Cruz’s dad was friends with JFK assassin Lee Harvey Oswald. Cruz denied his father had any involvement with Oswald.

During his speech Wednesday, Cruz urged people to “vote your conscience,” failing to endorse Trump or even mention him by name.

He was met with a chorus of jeers and boos. The audience chanted: “Endorse Trump! Endorse Trump!”

Heidi Cruz had to be escorted out by security as an angry crowd of Trump supporters taunted her following the speech.

A video posted to Twitter showed Heidi, who works for Goldman Sachs, being shouted down by a group chanting her employer's name as she left:

When reporters tried to ask her questions as she left the arena, she said: “I don’t talk to the media, thanks.”

Trump did his best to steal Cruz's big moment with a dramatic appearance at Quicken Loans Arena just as his former rival was finishing his speech.

Trump later tweeted:

Wow, Ted Cruz got booed off the stage, didn't honor the pledge! I saw his speech two hours early but let him speak anyway. No big deal!
