Along with rescissions hitting foreign aid, the new round of firings shows Trump is still bent on tearing down bipartisan foreign-policy traditions.

The U.S. Supreme Court on Tuesday cleared the way for Donald Trump's administration to pursue mass government job cuts and the sweeping downsizing of numerous agencies, a decision that could lead to tens of thousands of layoffs while dramatically reshaping the federal bureaucracy.

The layoffs affect 1,107 civil service employees and 246 foreign service officers based in the United States, according to internal department notices and a senior official.
