So this happened today. Via Politico:
A day after accepting the Republican Party’s nomination for president, Donald Trump rehashed a conspiracy theory that claims the man who killed President John F. Kennedy once cavorted with Ted Cruz’s father.
“I don’t know his father. I met him once. I think he’s a lovely guy,” Trump said at a morning-after rally in Cleveland. “All I did is point out the fact that on the cover of the National Enquirer there was a picture of him and crazy Lee Harvey Oswald having breakfast.”
“This was a magazine that, in many respects, should be well respected,” Trump said. “I mean if that was The New York Times, they would have gotten Pulitzer Prizes for their reporting.”
