HOLLAND, Mich. -- Mitt Romney says Florida. Sen. Marco Rubio is being "thoroughly vetted" for vice president.
The comments came Tuesday amid reports by ABC News and The Washington Post citing unnamed advisers that Rubio isn't being vetted for the No. 2 spot on the GOP ticket.
Romney told reporters Tuesday evening that he "can't imagine" who the advisers are. He says the reports are false.
