The amendment acknowledged progress against Islamic State and al Qaeda in Syria and Afghanistan but warned that “a precipitous withdrawal” could destabilize the region and create a vacuum that could be filled by Iran or Russia.
It called on the Trump administration to certify conditions had been met for the groups’ “enduring defeat” before any significant withdrawal from Syria or Afghanistan.
Passage was expected after the Senate voted to advance it in a procedural vote last week. After concerns from some Democrats, the Senate approved a change to the bill making it clear the amendment was not intended to be a declaration of war or authorization to use military force.
Senator Jim Risch, the Republican chairman of the Senate Foreign Relations Committee, disputed before Monday’s vote that the amendment rebuked or insulted Trump. “As I read it, it recognizes … his effort for us to examine exactly what we are doing in these places,” Risch said.
