The FBI and IRS want more information about a half a million dollars in questionable credit card charges.
The charges date back to 2007 when former Chairman Jim Greer ran the state GOP. Greer has been indicted; so has former House Speaker Ray Sansom.
Both former leaders had party issued credit cards. Governor Charlie Crist, who left the party early this year, didn't have a party card. He says he's in the clear.
"Number one, justice is extremely important to have done and I know and have great confidence that the federal and state authorities that are looking into those continuing issues will do a very thorough job and I compliment them on their work," said Governor Crist.
The Republican Party of Florida isn't commenting on the subpoena, but in the past the party has pointed out that the time period in of allegations was during Greer's watch.
Greer resigned early this year under pressure from party faithful, and state senator John Thrasher is now at the helm.
A paper shredding truck was seen outside Republican Party headquarters on the day that Greer resigned.
