Manchester, New Hampshire (CNN) - New Hampshire Rep. Charlie Bass will endorse Mitt Romney Monday, one day after the former Massachusetts governor earned the support of the state's Republican senator.
Bass will announce his support for Romney at a morning rally in Nashua.
Programming note: GOP presidential candidates face off at 8 p.m. ET Tuesday, November 22, in the CNN Republican National Security Debate in Washington, D.C.
The move comes during a four-day swing through New Hampshire for Romney as he seeks to seal up his lead in the state where he has campaigned frequently and owns a summer home.
Bass, who is one of the state's two congressmen, served in Congress from 1995 to 2007 and was elected to Congress again in 2010.
He comes from a prominent political family in the state.
“Voters in New Hampshire and across our country are looking for a candidate that understands what our economy needs to recover and grow, that has the experience of creating jobs, and has the leadership qualities needed to bring the citizens of our nation back together in these challenging times,” Bass said in a campaign release. “I firmly believe that Mitt Romney is the candidate that will renew our country's faith in the American Dream."
The campaign announced he will also serve as co-chair of Romney's state steering committee and join the national steering committee.
Sen. Kelly Ayotte endorsed Romney Sunday, in a closely-watched decision and a major coup for the presidential candidate.
