Marco Rubio (Sort of) Endorses Ted Cruz, Shuts Down VP Speculation

Marco Rubio also ruled out being Donald Trump's VP pick.

"I hope that they’ll nominate a conservative," Rubio said. "The only one [presidential candidate] that fits that criteria is Ted Cruz.”

"Who is going to get voted off the island this week?" Rubio said.

Despite Rubio's half-hearted endorsement of the Texas senator, he has not completely withdrawn from the race. By suspending his campaign, the delegates he collected during the primary will still be bound to him on the first ballot of an open convention.

“I’m not going to be the vice president," the Florida senator said.
