(CNN) - Mississippi Gov. Haley Barbour's political action committee made a big hire Monday, naming veteran South Carolina political operative Jim Dyke as communications advisor, according to a press release.
The move is the latest step taken by the Republican governor toward a bid for the White House in 2012.
Dyke, who has worked on four presidential campaigns, served as communications adviser to President George W. Bush and Senate Majority Leader Bill Frist, as well as communications director at the Republican National Committee.
"Haley is delighted to have someone as talented as Jim Dyke joining his team to help us manage the increased national media interest and demand in the governor," PAC Treasurer Henry Barbour said in a statement. "Jim's knowledge and experience will prove invaluable to Haley in the coming few months."
