That's the word from the Associated Press:

Florida Sen. Mel Martinez, the first-term lawmaker who previously served in President Bush's Cabinet, will assume the chairmanship of the Republican National Committee, GOP officials said Monday.

Martinez, 60, will replace current chairman Ken Mehlman, who will leave the post in January at the end of his two-year term, said the officials, who spoke on condition of anonymity to avoid pre-empting a formal announcement.

Martinez will remain in the Senate. Mike Duncan, the RNC's current general counsel and a former party treasurer, will run the day-to-day operations at the party's Capitol Hill headquarters.
