From the press release:
U.S. Senator Russ Feingold (D-WI) and Senate Majority Leader Harry Reid (D-NV) announced today that they are introducing legislation that will effectively end the current military mission in Iraq and begin the redeployment of U.S. forces. The bill requires the President to begin safely redeploying U.S.troops from Iraq 120 days from enactment, as required by the emergency supplemental spending bill the Senate passed last week. The bill ends funding for the war, with three narrow exceptions, effective March 31, 2008.
