The Office of Management and Budget sent a letter to the State Department and the U.S. Agency for International Development on Saturday, notifying them of the action, which took effect one minute before midnight that day.

Duffey, the associate director for national security programs at OMB, wrote that no more money can be obligated from those funds until three days after OMB receives the numbers, a process that could take days if not weeks.
