COLUMBIA — Minnesota Rep. Michele Bachmann has added an adviser to her South Carolina presidential campaign.

Bachmann said Wednesday that Wesley Donehue has joined her team. The outspoken Republican activist will serve as a spokesman and strategist, as well as help the national new media team.

Donehue joins senior adviser Ron Thomas and state campaign director Sheri Few.

Bachmann is trailing in support in South Carolina after months of being an early favorite. The announcement comes after weeks of changes in her campaign elsewhere.

Donehue is the spokesman for the state Senate’s Republican caucus and has a political consulting business.

Thomas’ positions with the state Republican Party include state political director and second vice chairman. Former President George Bush appointed him as deputy assistant secretary in the Department of Veterans Affairs.
