The National Republican Congressional Committee is getting an early start on its 2014 campaign to keep the GOP in charge of the House.

National and local GOP officials launched a mobile billboard campaign Tuesday targeting Democratic U.S. Reps. Ann Kirkpatrick and Ron Barber for supporting the national health care law.

Kirkpatrick represents District 1, which runs from the Utah line on the north, down the eastern boundary of the state and into northernmost Pima County. She served one term in the U.S. House before losing a re-election bid in 2010 to Republican Paul Gosar.

Gosar ran for re-election in a different district in 2012 following redistricting, and Kirkpatrick beat Republican Jonathan Paton in November to return to Congress.

Barber was also elected in November, defeating the GOP's Martha McSally in Congressional District 2, which covers the eastern half of Tucson and all of Cochise County. Barber served as an aide to former Congresswoman Gabrielle Giffords until she resigned following the January 2011 shooting in which both she and Barber were wounded.
