Washington D.C. (AP) — The White House and Senate leaders of both parties have agreed on unprecedented emergency legislation to rush sweeping aid to businesses, workers and a health care system slammed by the coronavirus pandemic. The urgently needed pandemic response measure is the largest economic rescue measure in history. It’s intended as a weeks- or months-long patch for an economy spiraling into recession and a nation facing a potentially ghastly toll. Top White House aide Eric Ueland announced the agreement in a Capitol hallway shortly after midnight, capping days of often intense haggling and mounting pressure. The package still needs to be finalized in detailed legislative language.
