(CNN) – Rep. Sue Myrick of North Carolina, the first Republican woman to represent the state in Congress, announced Tuesday she will not seek re-election.
"Thanks for the trust you have placed in us all these years," Myrick said in a statement on her Facebook page. "We will spend the rest of the year working on the issues that are important to all of you – and I hope to be a positive influence in all our negotiations."

The nine-term congresswoman represents North Carolina's 9th Congressional District, which includes portions of Gaston, Union and Mecklenburg Counties. Prior to her years on Capitol Hill, she served as mayor of Charlotte.
She's the third House member from the state to announce a decision against running for re-election. Following the results of a new redistricting map, Democratic Reps. Brad Miller and Heath Shuler also retire after completing their terms in 2013.
Democratic Gov. Bev Perdue, who was expected to face a tough battle for re-election in the fall, also recently announced she will not run.
Myrick is the 15th Republican to pass on a House re-election bid, while 20 Democrats will not be seeking to keep their seats.
Democrats need 25 seats to re-capture the chamber.
