"This can never happen again," Treasury Secretary Jacob Lew said.
Added Senate Republican Leader Mitch McConnell, "There'll not be another government shutdown, you can count on that."
The 16-day partial shutdown ended last week although a possible repeat may be on the horizon. Lawmakers approved a budget that keeps the lights on through January 15 and lets Treasury continue to pay its bills through February 7.
That's not to say there is a solution at hand, and no one is rushing forward with alternatives to a potential repeat of the gridlock that shuttered parts of the government and pushed the US to the brink of a default on its debt. The political price has been high ahead of 2014's midterm elections, especially for Republicans.

Democratic House Leader Nancy Pelosi reiterated the public's reaction to the partisan gamesmanship that played out over more than two weeks: "I join the American people in their disgust at what happened in terms of the shutdown of government."
But there's no real way forward to dodge a repeat and its chief architect, Republican Sen Ted of Cruz, is urging one. Hundreds of thousands of government workers were sent home amid the shutdown and national parks were barricaded while politicians negotiated.

"We just went through an awful period for our country," said Republican Sen Lindsey Graham.
A standoff between President Barack Obama and a group of congressional Republicans over spending for the budget year beginning October 1 and defunding the nation's health care overhaul led to the shutdown. Lawmakers also pushed the country to the edge of economic default by threatening the Treasury Department's authority to continue borrowing the money needed to pay the nation's bills.
