The transfer of responsibility for detention operations has not progressed as rapidly as we would like to the Iraqis, so there's a need to have that force sustained, as well," Ham said.
President Bush ordered nearly 30,000 additional troops to Iraq in January 2007 to pacify Baghdad and its surrounding provinces. When the last of the five Army combat brigades and two Marine battalions ordered in as part of that campaign leave Iraq by July, 140,000 troops will remain -- about 8,000 more than the 132,000 U.S. troops stationed there before the surge, Ham told reporters at the Pentagon.
