Wshington: The US Senate adjourned late Sunday without reaching a deal on re-opening government, as the Republican leadership postponed a vote on ending the shutdown until noon on Monday.

Senate Majority Leader Mitch McConnell had sought to move up a 1:00 am (0600 GMT) Monday vote to 10:00 pm Sunday night, but top Senate Democrat Chuck Schumer objected.

He said that despite continuing negotiations, "we have yet to reach agreement on a path forward that will be acceptable for both sides."

The postponement to mid-day Monday means the United States will begin its upcoming work week with much of the federal government shuttered.
