The groups that sued insist the court’s ruling ought to force the Trump administration to restore all funding delivered via U.S.A.I.D. But the administration says it has the power to decimate the agency.

A day after getting a boost from the Supreme Court, U.S. foreign aid contractors and grant recipients go before a federal judge on Thursday to try to restore funding halted by President Donald Trump's administration in his drive to shut down American humanitarian efforts globally.

The justices split 5-4 on whether to halt a judge’s order to restart nearly $2 billion in State Department and USAID payments for work that has been done.
