Yahoo News/Reuters:  U.S. Iraq envoy warns skeptical Senators on pullout[*1] :

The U.S. ambassador to Iraq warned skeptical senators on Thursday against an unconditional withdrawal of American troops but was told, in the words of one influential Democrat, “We ain’t staying.”

Sen. George Voinovich of Ohio, a Republican who has distanced himself from Bush’s Iraq policy, bluntly told Crocker: “We have to disengage. It’s inevitable.”

Sen. Joseph Biden, a 2008 Democratic presidential hopeful from Delaware who chairs the committee, chimed in: “Listen to the Republicans. We ain’t staying. We’re not staying. We’re not staying. Not much time.”
