ABC's Jonathan Karl reports that Marco Rubio is not being vetted to be Mitt Romney's running mate:
Even before the Republicans chose a presidential nominee it was widely assumed that Sen. Marco Rubio, R-Fla., would be at the top of anybody’s list of vice presidential candidates. The reasons are obvious: Not only is he young, charismatic and wildly popular with conservatives, but he could also help Republicans win a key state (Florida) and make inroads with Hispanics.
But knowledgeable Republican sources tell me that Rubio is not being vetted by Mitt Romney’s vice presidential search team. He has not been asked to complete any questionnaires or been asked to turn over any financial documents typically required of potential vice presidential candidates.
Although it is possible that Rubio may yet be asked to go through the vetting process, it has been nearly two months since Romney named his long-time aide Beth Myers to run his vice presidential search. The fact that Rubio has not been asked to turn over any documents by now is a strong indication that he is not on Romney’s short list of potential running mates.
Rubio's autobiography, An American Son, is being released today.
