Breaking: House to vote on Iraq withdrawal today.

“In a change of plans, House Democratic leaders today plan to bring up legislation that would begin redeployment of U.S. forces and contractors from Iraq not later than 90 days after enactment and to be completed within 180 days before turning to a second Iraq war supplemental,” National Journal reports.

The bill was introduced Wednesday night by Rep. Jim McGovern, D-Mass., a prominent member of the Out of Iraq Caucus, after discussions with Speaker Pelosi.

The vote on the McGovern bill is a concession to antiwar members of the Democratic Caucus who are concerned that supplemental proposed by Appropriations Chairman Obey would not permit until July an up-or-down vote on removing troops from combat zones.

UPDATE: Greg Sargent has some additional details.
