Congress is set to mount a fresh challenge to President Donald Trump’s war authorities just weeks after he announced that US troops would leave Syria.

Progressive Democratic Rep. Barbara Lee of California is looking for co-sponsors on legislation to sunset the 2001 Authorization for Use of Military Force within eight months. If enacted, the bill would force the Pentagon to seek new legal clearance to fight in Iraq and Syria, for instance.

The Bay Area Democrat was the lone vote in either chamber against the war authorization passed in response to the Sept. 11, 2001, terrorist attacks that paved the way for the US ground fight in Afghanistan. To this day she maintains that the authorization has given the White House an overly broad remit to wage war in the Middle East.

“For 17 years, presidents have relied on the overly broad 2001 war authorization to wage open-ended wars around the world,” Lee told Al-Monitor in a statement. “Congress has been missing in action on this issue for far too long, and I will keep working with my colleagues — on both sides of the aisle — to restore congressional oversight on matters of war and peace.”
