WASHINGTON (AP) — The Senate is taking the first steps toward repealing two measures that give open-ended approval for military action in Iraq. The push to end that authority comes as the United States marks the 20th anniversary of the Iraq War. Senators plan a procedural vote Thursday on legislation that would repeal the 2002 measure that greenlighted that March 2003 invasion of Iraq. And a vote is expected on repealing a 1991 measure that sanctioned the U.S.-led Gulf War to expel Iraqi leader Saddam Hussein’s forces from Kuwait. A bipartisan group of lawmakers has long sought to reclaim congressional powers over U.S. military strikes and deployments.
