President Trump’s administration has told the State Department to cut more than 50 percent of U.S. funding to United Nations programs, Foreign Policy reported.

The push for the drastic reductions comes as the White House is scheduled to release its 2018 topline budget proposal Thursday, which is expected to include a 37 percent cut to the State Department and U.S. Agency for International Development budgets.

It's not clear if Trump's budget plan, from the Office of Management and Budget, would reflect the full extent of Trump's proposed cuts to the U.N.

Secretary of State Rex Tillerson has suggested phasing in the major reductions over the coming three years.

One official close the administration told Foreign Policy that Tillerson has flexibility about how best to implement the reduction.

The U.S. spends roughly $10 billion annually on the U.N., and the cuts could have the greatest impact on peacekeeping, the U.N. development program and UNICEF, which are funded by State's Bureau of International Organization Affairs.

The fate of other popular programs, like the World Food Programme and U.N. refugee operations, are less clear. The World Food Programme's funding comes from the Department of Agriculture.

The magazine said it confirmed the potential cuts with three sources; one said the administration is considering cutting humanitarian aid programs by 36 percent.

Richard Gowan, a U.N. expert at the European Council on Foreign Relations, said the alterations would spark “chaos” if true.
