In a n exclusive interview with CBS, Rubio explained why he started the attacks.

“So we waited as long as we could cause I prefer not to do that sort of thing,” he said. “But I’m not going to allow the party of Reagan and the conservative movement to be taken over by someone who isn’t just a conservative but is a con artist.”
