The House voted 268-161 on Thursday to repeal the 2002 Authorization for the Use of Military Force (AUMF) in Iraq, almost two decades after the resolution was first passed by Congress.
Why it matters: If passed by the Senate, the repeal of the AUMF would prevent U.S. presidents from carrying out attacks in Iraq without securing prior approval from Congress. The House also voted to repeal AUMF last year, but the measure was not taken up in the Senate and the Trump administration opposed the move.
49 Republicans voted in favor of the repeal this year — only 10 had supported it during last year's House vote.
The big picture: At the height of the Iraq War, over 150,000 service members were stationed in Iraq. The U.S. pulled 2,200 troops from Iraq last year, returning troop levels in the country to about the same number in 2015.
