At midnight, for the first time in 17 years, the federal government shut down. A game of legislative ping-pong continued into Tuesday morning as House Republicans sought to delay Obamacare and the Senate declined to follow suit. The ball was in the House’s court when the clock struck midnight. The lower chamber had voted to approve the latest GOP continuing resolution by a vote of 228-201 on Monday evening. Twelve Republicans voted against the bill, and nine Democrats voted for it. About a half an hour later, the Senate rejected the GOP continuing resolution and set it back to the House, making a shutdown inevitable. At the moment that the shutdown took effect, the House was debating a motion to go into conference with the Senate on the continuing resolution—a measure Majority Leader Harry Reid had already announced he would reject.
