The Republican-run House has rejected an effort by Democrats to force a quick end to the partial government shutdown.
By a 227-197 vote Wednesday, the House rejected a move by Democrats aimed at forcing the House to vote on immediately reopening the government without clamping any restrictions on President Barack Obama's health care law.
The Democratic-run Senate has already approved such legislation.
House Republican leaders have refused to allow their chamber to vote on that plan. They have approved legislation that would reopen government, but only with a one-year delay in the health care law's requirement that individuals purchase health insurance.
The partial shutdown began Tuesday.
His spokesman says President Obama isn't backing down from his refusal to negotiate changes in the health care law in return for reopening the government.
Obama has called Democratic and Republican congressional leaders to the White House. Spokesman Jay Carney says he'll be impressing upon them the consequences of the shutdown, but won't be offering what Carney calls "concessions to Republicans in exchange for not tanking the economy."
House Speaker John Boehner's office had suggested the meeting was a sign that Obama is ready to yield. A spokesman for the speaker said Obama realized that "his refusal to negotiate is indefensible."
Also attending the meeting will be Senate GOP leader Mitch McConnell, and the Democratic leaders of the Senate and House, Harry Reid and Nancy Pelosi.
Reid today offered a new round of budget talks to House Republicans if they allow the government to reopen. But a spokesman for Boehner said he rejected the offer.
