WASHINGTON – The Senate moved ahead Wednesday toward a vote on a huge, bipartisan spending bill aimed at keeping the government running through September and ruling out the chance of a government shutdown later this month.

Chamber leaders announced Wednesday afternoon that a logjam that has stalled the bill since Tuesday had been broken and that the measure would pass by late afternoon and return to the House, where a vote on Thursday would send it to President Barack Obama for his signature.

A vote was scheduled on an amendment by Tom Coburn, R-Okla., that is aimed at shifting money within the National Park Service to try to make sure the White House remains open to tours. But even if it's approved, the amendment would appear to fail to accomplish its goal since the reason for closing the White House tours were cuts to the Secret Service, not the Park Service.
