MINNEAPOLIS (AP) - Rep. Michele Bachmann has named Chase Kroll to run her campaign for a fourth term in the U.S. House.

Kroll was political director for Bachmann's 2010 campaign, a 13-point victory over Democrat Tarryl Clark. He also worked on her 2008 campaign.

Kroll most recently worked as a legislative adviser in Bachmann's Washington office.

He joins just as another staffer, Andy Parrish, departs. Parrish worked on Bachmann's presidential campaign last year before eventually rejoining her congressional staff as a special projects coordinator.

No Democrats have announced plans to run against Bachmann pending new redistricting maps expected later this month.
