Treasury Secretary Timothy Geithner boldly predicted that Congress will vote to raise the debt ceiling next month, warning that failure to do so would bring "catastrophic" consequences for the U.S. and global economies.
Geithner, appearing on ABC's "This Week," said that if House Republicans were to push the vote to the brink or fail to raise the limit, it would "make the last [financial] crisis look like a tame, modest crisis."
Geithner said that Republicans have told President Obama they "recognize we have to do this, and we're not going to play around with it."
Geithner said the Republican leadership assured Obama in a meeting at the White House on Wednesday that it understands the gravity of the debt-ceiling situation and will vote to raise it.
"The responsible people up there understand that," Geithner said.
But Republicans appearing on the Sunday talk shows demonstrated how tough a fight the White House might be facing just weeks after a near-shutdown of the government spurred by debates over fiscal 2011 spending.

Ryan said that, as he understands it, GOP leaders have told the White House: “In addition to raising the debt limit, we want financial controls, we want cuts in spending accompanying the raising of the debt ceiling.”

Coburn: I won’t challenge Trump, I’ll vote for him Coburn: I haven't seen 'self-discipline' from Trump MORE (R-Okla.), a member of the Senate Gang of Six negotiations, and Rep. Chris Van Hollen (D-Md.), newly named to the Biden budget talks by House Minority Leader Nancy Pelosi (D-Calif.), previewed the battle to come, with Coburn making clear that he and other Republicans will not vote to raise the debt ceiling without an agreement on cuts.
Coburn made plain that he will not accept an increase in the nation's $14.3 trillion debt limit in the coming weeks without agreement on a debt-reduction package.
“What do I need? I need absolute certainty that we've made the critical changes that are necessary to put this country back where it needs to go. And unless we do that, there is no way I support it,” he said.
“We are going to have a debt crisis ... if we don't come together, so it's time to come together,” he said.
Van Hollen, the ranking member of the Budget Committee, said President Obama has laid out a “two-track” process whereby a "clean" debt-ceiling bill is passed and a deficit package is developed separately.

"I think we haven't yet determined what our strategy is going to be," the Tea Party favorite said, "but I can tell you that the people of Kentucky elected me to shake things up."
Geithner said that failing to raise the debt limit would result first in the U.S. stopping payments and benefits to seniors and veterans before risking default on interest loans.
Default, Geithner said, would have a "permanent devastating effect" on the nation's credit-worthiness.
"No responsible person" would play politics with the debt ceiling, Geithner said.
The White House has sent mixed signals about what Obama will accept in the debt-ceiling debate.
From the beginning, White House officials made a push for a "clean" bill raising the ceiling, but Obama has suggested in recent days that he would be open to coupling the debt ceiling with more spending cuts in an effort to satisfy the appetites of House Republicans.
Geithner said on NBC's "Meet the Press" that the White House will work parallel to the debt-ceiling debate to find other ways to cut spending, but "if we haven't worked all that out, we're still going to have to raise the debt limit."

Southerland and other conservative Republican lawmakers warned that before they will sign on to raising the debt ceiling, they want to see spending caps and other dramatic steps taken to cut spending.
"We've got to have some guarantees," Southerland said.
Geithner was also asked Sunday if he will stay on for a second term with Obama.
The Treasury secretary demurred, but indicated he was enjoying the job.
"I've got a lot on my plate still. We've got a lot of challenges ahead," Geithner said. "I'm going to keep at trying to fix what's broken here."
