In Congress, members of both parties were highly critical of the President's decision to pull back U.S. troops, which sparked the resignation last year of Defense Secretary James Mattis.
"Withdrawing U.S. forces from northern Syria is a catastrophic mistake that puts our gains against ISIS at risk and threatens America’s national security,"" said Rep. Liz Cheney (R-WY).
"If I'm an ISIS fighter, I've got a second lease on life," said Sen. Lindsey Graham (R-SC), who went on Fox News in what seemed like a bid to send his message of disapproval straight to the President.
"This impulsive decision by the President has undone all the gains we've made," Graham said on "Fox and Friends."
A number of Democrats also made their objections clear.
"Today’s announcement of a pullback of U.S. forces will undo all the hard fought gains of the U.S. military and its partners in the region,” said Sen. Jeanne Shaheen (D-NH).
But for others, the President is simply following through on a campaign pledge to stop what critics say are 'endless wars' in places like Syria and Afghanistan.
"I stand with @realDonaldTrump today as he once again fulfills his promises to stop our endless wars and have a true America First foreign policy," tweeted Sen. Rand Paul (R-KY).
