WASHINGTON (CNN) – Florida Gov. Charlie Crist has rolled out a succession of endorsements from national Republicans since announcing his entrance into the 2010 Senate race.
Now his Republican primary rival, former Florida House speaker Marco Rubio, has a national endorsement of his own from a conservative heavyweight: Mike Huckabee.
The former Arkansas governor will formally endorse Rubio in about two weeks, according to a Florida Republican familiar with the plans. The details of where the endorsement will take place have not been decided.
Rubio endorsed Huckabee's presidential bid in late 2007.
Huckabee's political action committee accidentally revealed the endorsement plans in an email to supporters on Tuesday evening that solicited donations for "candidates for Senate Huck PAC endorses."
"Candidates such as Marco Rubio of Florida," the e-mail said.
Rubio's campaign picked up another endorsement closer to home on Wednesday, that of Jeb Bush, Jr., the son of former Florida Gov. Jeb Bush.
The former governor, who remains popular among Republicans in Florida and nationally, is a Rubio mentor, but he has so far avoided weighing in on the Senate race.
