With members of Congress still working to reach an agreement on spending, the U.S. government shut down at 12 a.m. ET on Tuesday.
Sylvia M. Burwell, director of the Office of Management and Budget, ordered executive agencies to shut down just before midnight on Monday.
"We urge Congress to act quickly to pass a Continuing Resolution to provide a short-term bridge that ensures sufficient time to pass a budget for the remainder of the fiscal year, and to restore the operation of critical public services and programs that will be impacted by a lapse in appropriations," the memo said.
"This is a very sad day for our country," Senate Majority Leader Harry Reid (D-Nev.) said on the Senate floor early Tuesday morning. Reid declared the Senate is in recess until 9:30 a.m. Tuesday.
An estimated 800,000 federal workers face furloughs because of the shutdown, though many were told to work a half day Tuesday. POST
