Yet it seemed the endgame was at hand in the crises that have bedeviled the divided government for weeks, rattled markets in the U.S. and overseas and locked 350,000 furloughed federal workers out of their jobs. Both sides expressed fresh hopes for a resolution soon.
The up-and-down day also featured a dour warning from Treasury Secretary Jack Lew, who told lawmakers that the prospect of default had already caused interest rates to rise — and that worse lay ahead.
Appearing before the Senate Finance Committee, Lew said the Treasury must pay Social Security and veterans benefits as well as salaries to active duty military troops during the second half of this month. He said failure to raise the $16.7 trillion debt limit by Oct. 17 "could put timely payment of all of these at risk."
Senate Majority Leader Harry Reid advanced legislation to simply raise the debt limit and stave off the threat of an unprecedented federal financial default — a measure that Republicans are likely to block unless he agrees to change it.
Across the Capitol, Boehner left open the possibility of launching a rival measure in the House on Friday.
As he described it for his rank and file in a closed-door morning session in the Capitol, it would leave the shutdown in place while raising the nation's $16.7 trillion debt limit and setting up negotiations between the GOP and the president over spending cuts and other issues.
At the White House, spokesman Jay Carney told reporters the president would "likely sign" a short-term extension in the debt ceiling, and did not rule out his doing so even if it left the shutdown intact.
Reid wasn't nearly as amenable. "Not going to happen," he said brusquely.
By the time House Republicans had returned from the White House hours later, Rep. Hal Rogers, R-Ky., said part of their hope was to "quickly settle" on legislation to permit the government to reopen.
Rogers, the chairman of the House Appropriations Committee, told reporters it was clear Obama would "like to have the shutdown stopped ... and we're trying to find out what he would insist upon in the (legislation) and what we would insist upon."
Heartened by any hint of progress, Wall Street chose to accentuate the positive. After days of decline, the Dow Jones industrial average soared 323 points on hopes that the divided government was taking steps to avoid a default. Reid's dismissive comments at the White House came at the end of the trading day.
After more than a week of lost tourism, some governors prevailed on the Obama administration to let states use their own money to pay for national parks to reopen, Grand Canyon and Zion among them. There was a catch — the Interior Department made it clear it didn't plan to reimburse the states after the shutdown ends.
Senate Republicans forged ahead on an alternative of their own that would ease both the debt-limit and shutdown crises at once. Officials said that it would require Obama to agree to some relatively modest changes to the health care law that stands as his signature domestic achievement.
