WASHINGTON – The Republican-controlled U.S. House of Representatives passed a temporary funding bill to keep the government running Friday but tied it to an attempt to cripple President Barack Obama’s landmark health care overhaul — a risky ploy that threatens a partial shutdown of the government in a week and a half.

The stopgap funding measure needs to pass by the Oct. 1 start of the fiscal year to keep the government fully functioning. Typically, such measures advance with sweeping bipartisan support, but conservative tea party activists forced Republican leaders — against their better judgment — to add a provision to defund the health care law, the signature accomplishment of Obama’s first term.

The House vote sets the stage for a confrontation with the Democratic-controlled Senate, which promises to strip that provision from the bill this week. It will challenge the House to pass it as a simple, straightforward funding bill that Obama will sign.

Obama responded furiously Friday, accusing Republicans who voted against his health care law of focusing on politics and “holding the whole country hostage.”

“We’re not some banana republic. This isn’t some deadbeat nation,” Obama said before workers at a Missouri auto plant. “The entire world looks to us to make sure the world economy is stable. We can’t just not pay our bills. And even threatening something like that is the height of irresponsibility.”

Obama, who has said repeatedly he will not negotiate over debt limit legislation, called Boehner late in the day to tell him that directly. The speaker expressed disappointment, his office said, and responded that Congress “will chart the path ahead.”

Obama responded in remarks before an audience at a Ford assembly plant near Kansas City, Mo. He blamed a “faction on the far right of the Republican Party” for threatening to shut down government operations or default on government debts. “They’re focused on trying to mess with me,” he told plant workers. “They’re not focused on you.”
