Rep. John Murtha (D-Pa.), one of the leading anti-war voices in the House Democratic Caucus, is back from a trip to Iraq and he now says the "surge is working." This could be a huge problem for Speaker Nancy Pelosi (D-Calif.) and other Democratic leaders, who are blocking approval of the full $200 billion being sought by President Bush for combat operations in Iraq in 2008.

Murtha's latest comments are also a stark reversal from what he said earlier in the year. The Pennsylvania Democrat, who chairs the powerful Defense subcommittee on the House Appropriations Committee, has previously stated that the surge "is not working" and the United States faced a military disaster in Iraq.

"They [the White House] keep saying the news media is being negative," Murtha said. "They keep making excuses for the lack of progress. I've been hearing this month after month and I'm absolutely convinced right now the surge isn't working and I'm convinced that if they don't pay attention to what I'm saying and a lot of other members of Congress are saying they're going to have a disaster on their hands because the American public want the troops out of Iraq."

But Pelosi, who is scheduled to speak to a Democratic National Committee event in Virginia on Friday, will surely face tough questions from reporters regarding Murtha's statement on the surge.

"This could be a real headache for us," said one top House Democratic aide, speaking on the condition of anonymity. "Pelosi is going to be furious."

Compromising and capitulating are the only things the Democrats have been doing on this issue. Murtha's statement implies that some sort of deal can be reached with the Republicans in which a somewhat extended troop withdrawal timetable will be agreed upon. During his press conference, Murtha suggested that might be something like a two year calendar.

“With one of the Democrats’ leading war critics now saying the surge in Iraq is working, it’s difficult to understand why the majority continues to push an irresponsible withdrawal plan that jeopardizes critical support funding for our troops. It can’t be the facts on the ground that are influencing their decision-making: After all, our servicemen and women have made tremendous progress the past six months, with fewer attacks on our troops, greater security in historically insecure areas, and terrorist insurgents on the run.

“The stakes are too high for this Congress to remain idle on this critical funding bill. The Pentagon has continued to make clear the ongoing Democrats’ stranglehold over resources will force it to lay off staff, cut operations, and pare back the budgets of other departments. It’s time for the majority to stop playing games and deliver a well-deserved gift in time for Christmas to our men and women in uniform: a clean supplemental funding bill.”

On Friday, however, Murtha's office moved to clarify his seemingly positive take on the surge, this time putting it in the context of renewed criticism of the administration.

"The military surge has created a window of opportunity for the Iraqi government," Murtha's statement read. "Unfortunately, the sacrifice of our troops has not been met by the Iraqi government and they have failed to capitalize on the political and diplomatic steps that the surge was designed to provide.

"The fact remains that the war in Iraq cannot be won militarily, and that we must begin an orderly redeployment of U.S. forces from Iraq as soon as practicable."
