Fla. governor to endorse McCain
ORLANDO --Florida Gov. Charlie Crist will endorse John McCain, the Associated Press has learned, a move likely to give the Republican presidential candidate a critical boost ahead of Tuesday's primary.
The Arizona senator is locked in a tight race with Mitt Romney.
McCain was appearing with Crist at a county GOP event later Saturday, and the endorsement was to be announced there, according to Republican officials who spoke on the condition of anonimity.
