U.S. Sen. Marco Rubio, R-Fla., ripped into old rival former Gov. Charlie Crist on Monday. Crist announced on Monday that he was running for the Democratic nomination to challenge Gov. Rick Scott in 2014. Rubio caught Crist in the 2010 Republican U.S. Senate primary, chasing the then-governor out of the GOP and to continue his bid with no party affiliation. Crist joined the Democrats at the end of last year.
