The National Republican Congressional Committee will attack Rep. Carol Shea-Porter, D-N.H., in its first television advertisement of the 2014 cycle.
The committee put $20,000 behind the spot, which will air on a WMUR affiliate beginning Monday.
The spot criticizes Shea-Porter's opposition to the GOP-backed "no budget, no pay" bill, playing on her state's motto, "Live Free or Die."
Last November, Shea-Porter defeated then-Rep. Frank Guinta, the Republican who ousted her from Congress in 2010. She is expected to be a top target for Republicans in 2014.
Shea-Porter explained her vote to WMUR, which reported the ad buy on Friday.
"The wealthy people in the House and Senate can go without the pay, but others will be hurt along with their families for something that wasn't their decision," Shea-Porter told the affiliate.
