President Joe Biden conceded that he could not guarantee the United States will not default on its loans as debt ceiling negotiations with congressional Republicans stall.

"I can't guarantee that they wouldn't force a default by doing something outrageous," Biden told reporters Sunday of Republicans. "I can't guarantee that."

LIBERALS BLAME REPUBLICANS, NOT BIDEN, FOR THEIR PURSUIT OF DEBT CEILING 'PLAN B'

The president said he believes he can invoke the 14th Amendment but repeated concerns he has already expressed regarding whether the amendment, which stipulates U.S. debt "shall not be questioned," could be "invoked in time."

On the sidelines of the Group of Seven leaders meeting in Hiroshima, Japan, Biden suggested "MAGA Republicans in the House" were seeking to take political advantage of a default because it would devastate the economy and "that’s the one way to make sure Biden’s not reelected."

"I'm hoping that Speaker [Kevin] McCarthy is just waiting to negotiate with me when I get home, which I don't know whether that's true or not," he said.

Biden and McCarthy (R-CA) are expected to speak on the phone Sunday as the president returns to the White House on Air Force One.

In a wide-ranging press conference, Biden also told reporters to anticipate an improvement in the U.S.-China relationship, after saying "everything changed" when the latter directed a “silly balloon that carried two freight cars worth of spy equipment" over the continental U.S.

"I think you’re going to see that begin to thaw very shortly," he said.
