President Obama urged the House on Friday to pass a Senate bill that funds the government and warned once again that he would not negotiate away changes to the Affordable Care Act in exchange for raising the federal debt ceiling.

In his remarks, Obama was blunt, telling Republicans seeking concessions, including scaling back or defunding Obamacare, to "knock it off."

“Knock it off, pass a budget and move on,” Obama said, adding: “I encourage you to think about who you’re hurting.”

Shortly after the Senate passed a bill that keeps the the government operating past Monday, Obama told House leaders that they should do the same, leaving alone his signature health-care law.

Sometimes showing signs of dark amusement at the litany of Republican demands, Obama appealed to House conservatives to realize that they would be hurting military pay, students and families in their home districts if they allow the government to shut down.

Republicans have suggested that they will add new demands to the government funding bill Saturday before sending it back to the Senate, though their strategy was not fully clear.

The Senate has "acted responsibly by voting to keep our government open," Obama said. "So far the Republicans in the House of Representatives have refused to moved forward."

Obama also insisted that Republicans must raise the federal debt ceiling later next month without negotiations. He urged the GOP to separate the issue from their dislike of him personally.

"Nobody gets to threaten the full faith and credit of the United States just to win political concessions," he said.

"Voting for the Treasury to pay America's bills is not a concession," he added. "It is not a favor to me."

Responding to Obama’s statement Friday afternoon, aides to House Speaker John A. Boehner (R-Ohio) said the speaker hasn’t spoken with the president at all this week.

As about what Obama had to say, Boehner spokesman Brendan Buck said in an e-mail: “The House will take action that reflects the fundamental fact that Americans don’t want a government shutdown and they don’t want the train wreck that is Obamacare. Grandstanding from the president, who refuses to even be a part of the process, won’t bring Congress any closer to a resolution.”
