WEST PALM BEACH, Fla. (AP) - Former Florida Gov. Jeb Bush says he'd consider running as vice president with Mitt Romney, but doubts he'll ever be asked.

Bush tells the conservative website Newsmax that Florida Sen. Marco Rubio is "probably the best" choice to share the ticket with Romney, the presumptive GOP presidential nominee. Bush said he hopes the freshman senator is offered the No. 2 slot and accepts it.

Rubio has said repeatedly that he isn't interested in leaving the Senate.

Bush said he'd consider running if Romney were to ask him. But the former governor added that he's not sure running for vice president is the right thing for him and said he's doubtful he'd even receive the call.
