A sharply divided Supreme Court on Wednesday reinstated a lower-court order for the Trump administration to release frozen foreign aid, but it was not clear how quickly money would start flowing.

By a 5-4 vote, the court rejected an emergency appeal from the Republican administration, while also telling U.S. District Judge Amir Ali to clarify his earlier order that required the quick release of nearly $2 billion in aid for work that had already been done.

Although the outcome is a short-term loss for President Donald Trump’s administration, the nonprofit groups and businesses that sued are still waiting for the money they say they are owed. Organizations in the U.S. and around the world have cut services and laid off thousands of workers as a result.
