MoveOn working Obama on Afghanistan

Liberal group MoveOn is urging millions of its members to send a message to President Barack ObamaBarack ObamaTrump breaks with tradition, forgoes Ramadan dinner Trump: 'Why no action' from Obama on Russian meddling? Dems look to defense bill to put pressure on Trump MORE demanding an exit strategy from Afghanistan.

MoveOn's campaign will likely complicate Obama's efforts, as the president grapples with calls for more troops from military commanders and growing reluctance to put more boots on the ground from members of his own party in Congress.

In a Friday e-mail blast to almost 5 million members, MoveOn said: "Now, the majority of Americans — those of us who are for as quick and as responsible an end to the war as possible — need to make our voices heard, too.

"Can you write to the White House and tell them we need a clear exit strategy — not tens of thousands more U.S. troops stuck in a quagmire?"

MoveOn seized on recent comments by Vice President Joe BidenJoe BidenBiden rips Senate GOP healthcare bill, says it 'isn't about healthcare' Report: Biden scolded hedge fund manager over late son OPINION: Democrats are going to keep losing if they can't articulate a vision MORE and White House Chief of Staff Rahm Emanuel, who have urged caution on rushing to send more troops to Afghanistan "without a clear strategy."

MoveOn's campaign could also throw a wrench into next year's midterm elections and prompt Democrats in Congress to oppose Obama on any more troop increases.
