Rudy Giuliani has endorsed Marco Rubio for Florida's open Senate seat over an opponent he said broke a promise to support him in his presidential bid.
The former New York City mayor emphasized Rubio's trustworthiness at a campaign event Monday. Giuliani backed Rubio over Gov. Charlie Crist.
Giuliani worked hard to get Crist's endorsement in his 2008 presidential run, and said the governor promised he'd get it. Crist instead backed Sen. John McCain.
But Giuliani called Crist's snub "ancient history" and said it colored his view of the governor but did not determine his endorsement.
A spokeswoman for Crist did not immediately respond to calls seeking comment. Crist appeared to be the early front-runner in the race, but Rubio has pulled ahead in the polls in recent months.
