Rep. Christopher Carney (D-Pa.) reported for active duty Thursday at Langley Air Force Base in Virginia, where he will serve through Oct. 13.

Carney, one of three Members currently serving in uniform, has been in the Navy Reserve since 1995. He was promoted to commander last spring, and the promotion became official Sept. 1.

“Wearing the uniform is a duty the Congressman takes very seriously,— said Vincent Rongione, Carney’s communications director. “When you make a commitment to the military, it is not just an expectation but it is an honor to fulfill that commitment.—

The Pennsylvania Democrat will be involved with Predator and Reaper missions in Iraq and Afghanistan. All of his offices will remain open while he is serving.

The other two Members in uniform are Rep. Mark Kirk (R-Ill.), an intelligence officer in the Navy Reserve, and Rep. John Boccieri (D-Ohio), a major in the Air Force Reserve.
