For more than five weeks, the Trump administration has been working to take apart the United States Agency for International Development, through layoffs and contract terminations. On Wednesday, the Supreme Court weighed in on a piece of those efforts, rejecting President Trump’s emergency request to freeze nearly $2 billion in already completed foreign aid work.

Here are the major actions by the administration and the courts, as well as their effects on the agency’s work force, since Mr. Trump took office.

For now, the case over frozen aid payments will proceed in the lower court, which the Supreme Court said should clarify what the government must do while taking into account what is feasible. Those instructions suggest the case could return to the Supreme Court.

But much of what undergirds the practical future for the agency remains in limbo: Most of the agency’s workers are on leave or fired, as are staff workers at many of its partner organizations. And a majority of its contracts and awards have been terminated, leaving only about one-tenth of its former total number intact.
