WASHINGTON (AP) -- A conservative challenge to the president's health care law has the federal government teetering on the brink of a partial shutdown.
The Senate has the next move on must-do legislation required to keep the government open past midnight on Monday, and the Democratic-led chamber is expected to reject the latest effort from House Republicans to use a normally routine measure to attack President Barack Obama's signature health care law.
Congress was closed for the day on Sunday after a post-midnight vote in the GOP-run House to delay by a year key parts of the new health care law and repeal a tax on medical devices as the price for avoiding a shutdown. The Senate is slated to convene Monday afternoon just 10 hours before the shutdown deadline, and Majority Leader Harry Reid, D-Nev., has already promised that majority Democrats will kill the House's latest volley.
A House GOP leader, Rep. Kevin McCarthy of California, said the House would again rebuff the Senate's efforts to advance the short-term funding bill as a simple, "clean" measure shorn of anti-heath care reform provisions.
Since the last government shutdown 17 years ago, temporary funding bills known as continuing resolutions have been noncontroversial, with neither party willing to chance a shutdown to achieve legislative goals it couldn't otherwise win. But with health insurance exchanges set to open Tuesday, tea party Republicans are willing to take the risk in their drive to kill the law, so-called "Obamacare."
"You're going to shut down the government if you can't prevent millions of Americans from getting affordable care," said Rep. Chris Van Hollen, D-Md.
A leader of the tea party Republicans, Sen. Ted Cruz, R-Texas, insisted the blame rests with Senate Democrats.
"The House has twice now voted to keep the government open. And if we have a shutdown, it will only be because when the Senate comes back, Harry Reid says, `I refuse even to talk,'" said Cruz, who led a 21-hour broadside against allowing the temporary funding bill to advance if stripped clean of a tea party-backed provision to derail Obamacare. The effort failed.
The battle started with a House vote to pass the short-term funding bill with a provision that would have eliminated the federal dollars needed to put Obama's health care overhaul into place. The Senate voted along party lines to strip that out and set the measure back to the House.
The latest House bill, passed early Sunday by a near party-line vote of 231-192, sent back to the Senate two major changes: a one-year delay of key provisions of the health insurance law and repeal of a new tax on medical devices that partially funds it. The steps still go too far for the White House and its Democratic allies.
Senate rules often make it difficult to move quickly, but the chamber can act on the House's latest proposals by simply calling them up and killing them.
Eyes were turning to the House for its next move. A senior leader vowed the House would not simply give in to Democrats' demands to pass the Senate's "clean" funding bill.
"The House will get back together in enough time, send another provision not to shut the government down, but to fund it, and it will have a few other options in there for the Senate to look at again," said McCarthy, the No. 3 House Republican leader.
He suggested that House Republicans would try blocking a mandate that individuals buy health insurance or face a tax penalty, saying there might be some Democratic support in the Senate for that.
On the other hand, Democrats said the GOP's bravado may fade as the deadline to avert a shutdown nears.
Asked whether he could vote for a "clean" temporary funding bill, Rep. Raul Labrador, R-Idaho, said he couldn't. But Labrador added, "I think there's enough people in the Republican Party who are willing to do that. And I think that's what you're going to see."
A leading Senate GOP moderate called on her fellow Republicans to back down.
"I disagree with the strategy of linking Obamacare with the continuing functioning of government - a strategy that cannot possibly work," said Sen. Susan Collins, R-Maine.
McCarthy wouldn't say what changes Republicans might make. He appeared to suggest that a very short-term measure might pass at the last minute, but GOP aides said that was unlikely.
Republicans argued that Reid should have convened the Senate on Sunday.
Yet even some Republicans said privately they feared that Reid held the advantage in a fast-approaching end game.
Republicans argued that they had already made compromises; for instance, their latest measure would leave intact most parts of the health care law that have taken effect, including requiring insurance companies to cover people with pre-existing conditions and to let families' plans cover children up to age 26. They also would allow insurers to deny contraception coverage based on religious or moral objections.
Tea party lawmakers in the House - egged on by Cruz - forced GOP leaders to abandon an earlier plan
to deliver a "clean" stopgap spending bill to the Senate and move the fight to another must-do measure looming in mid-October: a bill to increase the government's borrowing cap to avert a market-rattling, first-ever default on U.S. obligations.
In the event lawmakers blow the Monday deadline, about 800,000 workers would be forced off the job without pay. Some critical services such as patrolling the borders, inspecting meat and controlling air traffic would continue. Social Security benefits would be sent, and the Medicare and Medicaid health care programs for the elderly and poor would continue to pay doctors and hospitals.
McCarthy appeared on "Fox News Sunday," while Cruz and Labrador were on NBC's "Meet the Press." Van Hollen appeared on CBS' "Face the Nation."
