Trump Defends Linking Cruz's Father to JFK Assassin

Republican front-runner Donald Trump today refused to apologize for citing an unsubstantiated report that Ted Cruz's father was photographed with the assassin of former President John F. Kennedy, saying no one has denied it.

"I don't think anybody denied it," he told ABC News' George Stephanopoulos on "Good Morning America."

Cruz and his father both denied the report Tuesday before Cruz dropped out of the 2016 race after losing the Indiana primary. The National Enquirer had published the story several weeks ago alleging that Rafael Cruz was pictured with Lee Harvey Oswald, but no other media outlet confirmed the same story.

"It's ludicrous. It's ludicrous. I was never in New Orleans at that time," Rafael Cruz told ABC's Tom Llamas yesterday. "That's typical of Donald Trump just attack and make all kinds of innuendo and attacks with no substance."

"Let's be clear. This is nuts," Cruz told reporters yesterday. "This is not a reasonable position. This is just kooky. And while I'm at it, I guess I should go ahead and admit, yes, my dad killed JFK, he is secretly Elvis and Jimmy Hoffa is buried in his backyard."

But Trump, who now faces an easy path to the Republican nomination, defended his comments.

"All I did was refer to it. I'm just referring to an article that appeared. It has nothing to do with me," he continued. "The National Enquirer gave you John Edwards. It gave you OJ Simpson. It gave you many, many things," he said. "I mean, you can't knock the National Enquirer. It's brought many things to light."
