The Office of Management and Budget instructed the State Department and the U.S. Agency for International Development earlier this month to provide a balance sheet of foreign aid projects that have not yet been funded. Unless Congress intervenes, the money may be returned to the U.S. Treasury at the end of fiscal year on Sept. 30.

A scramble is on to allocate the money before the administration announces the expected change, which would freeze the billions of dollars left.

In his previous two budgets, President Trump proposed steep cuts to foreign aid, but Congress restored them. Lawmakers from both parties view the last-minute move as a backdoor attempt to get the cuts, despite their objections, before they can do anything about them.
