RENEE MONTAGNE, Host:
As NPR's David Welna reports, lawmakers on both sides of the aisle are baulking at both the length of the Afghan War and its cost.
DAVID WELNA: New Jersey's Scott Garrett is one of 26 Republicans who joined nearly every Democrat in voting for the measure.
SCOTT GARRETT: I was never one, even when George Bush was in the White House, to say we should be engaged in nation building. I never thought that was the appropriate role of the United States. So now we've sort of checked - I don't know if it's simple to say we've check off that box, but it is a pretty important box that we checked off as far as getting bin Laden.
WELNA: Others have recently shifted their stance on Afghanistan.
NORM DICKS: You know, up here we have to kind of decide what the priorities are.
WELNA: As the top House Democrat on the defense spending panel, Washington's Norm Dicks was once a strong supporter of President Obama's troop surge. But now he's hoping for what he calls a substantial reduction of U.S. forces in Afghanistan.
DICKS: People are just - are having real concerns that this is going to go on for too long and then we're going to be there, you know, for another 10 years after 2014. And I just don't think that's sustainable.
WELNA: Nor does the number two Republican on the Senate Foreign Relations Committee, Tennessee's Bob Corker.
BOB CORKER: This is a massive nation-building effort, and I'm not sure - I don't think that's an effort that is sustainable nor one we should be involved in.
WELNA: Last week, 27 senators sent President Obama a letter calling for a shift in strategy in Afghanistan, and as they put it, a sizeable and sustained reduction of the U.S. forces there. Freshman Tea Party favorite Rand Paul of Kentucky is one of two Republicans who signed that letter.
RAND PAUL: I'd like the president to be more like the candidate.
WELNA: And say what?
PAUL: What he did as a candidate, that he'd like to end the war in Afghanistan.
WELNA: It was actually the war in Iraq that candidate Obama advocated ending. His GOP rival in that race, Arizona Senator John McCain, yesterday bemoaned the trend of more and more Republicans now opposing the war in Afghanistan.
JOHN MCCAIN: We are succeeding. They should listen to General Petraeus, just as we did in 2007, when then Senator Obama and then Senator Clinton said that we had to withdraw immediately from Iraq. We stayed the course; we succeeded.
WELNA: On the Senate floor Tuesday, West Virginia freshman Democrat Joe Manchin, said the U.S. should, by all means, declare success in Afghanistan - and go home.
JOE MANCHIN: I believe it is time for President Obama to begin a substantial and responsible reduction in our military presence in Afghanistan. I believe it is time for us to rebuild America, not Afghanistan.
WELNA: At the time, McCain, who was also on the floor, and he lashed out at Manchin.
MCCAIN: I feel compelled to respond to the statements by the senator from West Virginia, which characterized the isolationist, withdrawal, lack-of- knowledge-of-history attitude that seems to be on the rise in America.
WELNA: But Manchin was not backing down.
MANCHIN: We are a very hawkish state, as you know, and we're a very patriotic state. But if 10 years is not enough, how long is enough?
WELNA: Carl Levin, the Michigan Democrat who chairs the Senate Armed Services Committee, says he wants President Obama to announce a significant drawdown tonight - at a minimum, 15,000 troops by the end of this year.
CARL LEVIN: The Taliban use our presence there to both recruit and to build up support for their attacks on people, because they claim they're going after foreign occupiers. And if we have a significant reduction, we take away that argument of the Taliban, which has helped them, which means it has hurt us.
WELNA: David Welna, NPR News, the Capitol.
