The U.S. government started shutting down early Tuesday after a bitter fight over the new health care law deadlocked the Congress and stymied every attempt to keep money flowing after the federal fiscal year ended at midnight.
It was the first such collapse of the government in nearly two decades and there was no immediate way to know how long it would last or how it would end.
The partial closure will delay Social Security payments, passport and visa applications, shutter national parks and museums and furlough hundreds of thousands of federal employees. Essential services will still be provided; the military remains on duty.
President Barack Obama declared the government had officially run out of money for many services and operations when the fiscal year expired at 12:01 a.m. Tuesday.
