Trump was not.
He said it was ridiculous.
““His father was with Lee Harvey Oswald prior to Oswald’s being — you know, shot. I mean, the whole thing is ridiculous,” “
Where is ALL that he said, not just a select little bit?
Lol...Trump clearly enjoys needling his opponents, both political and in the media, while sucking all the air out of the news cycle. This story about a potential link between Cruz's father and Lee Harvey Oswald does all that and a whole lot more.
Notice he never says which part of the story he thinks is ridiculous either.
