The one bright spot on Monday is a significant chunk of the furloughed federal workforce is headed back to work. Defense Secretary Chuck Hagel ordered nearly 350,000 back on the job, basing his decision on a Pentagon interpretation of a law called the Pay Our Military Act.
Those who remain at home or are working without paychecks are a step closer to getting back pay once the partial government shutdown ends. The Senate could act this week on the measure that passed the House unanimously on Saturday.

"Let me issue him a friendly challenge. Put it on the floor Monday or Tuesday. I would bet there are the votes to pass it," said Sen. Chuck Schumer, D-N.Y.
In a series of Sunday television appearances, Lew warned that on Oct. 17, he exhausts the bookkeeping maneuvers he has been using to keep borrowing.
"I'm telling you that on the 17th, we run out of the ability to borrow, and Congress is playing with fire," Lew said.

Treasury issued a report on Thursday detailing in stark terms what could happen if the government actually defaulted on its obligations to service the national debt.
