"FILE - This Jan. 26, 2012 file photo shows former Florida Gov. Jeb Bush speaking in Miami. Bush is reiterating that he won't join Mitt Romney on the GOP presidential ticket. Bush says no one's asked him to submit personal documents to the team picking Romney's vice presidential nominee. He also says he's certain he won't be asked, either. Bush says he backs his ""friend"" and fellow Floridian, Sen. Marco Rubio. (AP Photo/Wilfredo Lee, File)"
