The Trump administration will keep approximately 400 U.S. troops in Syria — double the estimate the White House provided on Thursday, a new report says.

Although the majority of the 2,000 U.S. troops in Syria are poised to exit the region in the spring, a senior administration official told the Washington Post that approximately 400 troops will stay. The troops will be stationed in northeast Syria and in southern Syria near Jordan at the al Tanf garrison “for the foreseeable future.”
