According to a CBS News report, the State Department’s support for the White Helmets is “under active review”

Meanwhile Moscow would like to know the reasons for Washington’s decision and how much funding they have already recieved. This would mean a significant blow for the group, as the money accounts for about one-third of the White Helmets’ overall funding. An internal State Department document said that its Near East Bureau needed confirmation from the administration to green light funding for the White Helmets in Syria by April 15th or the department would initiate “shut-down procedures on a rolling basis.” That document also said that the department needed to be notified by April 6th that it could continue programs that focus on removing land mines, restoring essential services and providing food to moderate forces and their families or those programs would also have to be shut down. Just last month, US State Department spokesperson Heather Nauert called the group “an incredible group of individuals.” At that time, she also stated that as far as she was aware, the White Helmets were still being paid by Washington, despite a $200-million freeze in US funding for recovery efforts in Syria in late March.
The United States Department of State freezes funding to the White Helmets humanitarian group, which conducts urban search and rescue in rebel-held areas of Syria. The U.S. provides one-third of the group's total funding.
