Specifically, the GOP front-runner thinks Rafael Cruz may have had some sort of connection to the assassination of John F. Kennedy.

9 facts you should know about Ted Cruz:

The National Enquirer tabloid ran a story in April alleging the same thing, though with shaky evidence at best — a photo of Lee Harvey Oswald with an unidentified man the tabloid suggests is the elder Cruz.

But it's worth noting that even the experts the National Enquirer hired to analyze the picture wouldn't say the man is Rafael Cruz — just, basically, that it looks like him.

Cruz's campaign told McClatchy the claim was "another garbage story in a tabloid full of garbage." The National Enquirer, by the way, endorsed Trump last month.
