Senator Doug Jones (D-AL) has now weighed in on President Donald Trump’s decision to withdraw all American troops from northern Syria, saying the move “leaves a vacuum for a resurgence of [the Islamic State] in the region.”

The Trump administration is allowing Turkey to move forward with an operation against Kurdish forces in the region who have been allies in the fight against ISIS.

In a tweet on Monday afternoon, Jones remarked, “Kurdish fighters have been invaluable partners in our mission to defeat the Islamic State.”

“To abandon them in this moment leaves a vacuum for a resurgence of IS in the region,” Alabama’s junior senator continued.

Jones concluded, “This is an alarming move that sends the exact wrong message to our allies.”

Jones is a member of the U.S. Senate Committee on Armed Services.
