SUMMERVILLE, S.C. (AP) — A South Carolina House Republican is announcing her bid to oust U.S. House Rep. Mark Sanford next year, with the backing of two state legislative leaders.

Freshman Rep. Katie Arrington kicked off her race for Congress on Wednesday by calling South Carolina's former governor a career politician. Two other potential primary challengers have dropped their bid.

The Post and Courier of Charleston reports Arrington refused to answer questions from reporters at her announcement. House Speaker Jay Lucas of Hartsville and House Majority Leader Gary Simrill of Rock Hill endorsed her at the event. Both were in the House while Sanford was governor and continually berated his fellow Republicans.

Arrington first won seat last November. The 46-year-old Summerville resident replaced GOP Rep. Jenny Horne, who unsuccessfully challenged Sanford last year.
