WASHINGTON—

President Joe Biden said on Monday the federal government could breach its $28.4 trillion debt limit in a historic default unless Republicans join Democrats in voting to raise it in the two next weeks.

Senate Republicans, led by Minority Leader Mitch McConnell, have twice in recent weeks blocked action to raise the debt ceiling, saying they do want action but will not help by voting for the move. Republicans say Democrats can use a parliamentary maneuver known as budget reconciliation to act alone. Top Democrats have rejected that approach.

“Raising the debt limit comes down to paying what we already owe … not anything new,” Biden said at a White House news conference.

Asked if he could guarantee the United States won’t breach the debt limit, the president answered: “No, I can’t. That’s up to Mitch McConnell.” He said he intended to speak with McConnell about the matter.

McConnell for months has said that Democrats should use the budget reconciliation process to get around the Senate’s filibuster rule, which requires 60 of 100 members to agree to pass most legislation. Senate Majority Leader Chuck Schumer, a Democrat, has refused to use that approach, and Biden on Monday pleaded for Republicans not to block action with the filibuster.

“Just get out of the way,” Biden told Republicans. “If you don’t want to help save the country, get out of the way so you don’t destroy it.”

But Senator Joe Manchin, a moderate Democrat who has been at odds with many in his party on other major issues, said Democratic leaders should not rule out using budget reconciliation to raise the debt ceiling.

“Well they shouldn’t rule out anything – we just can’t let the debt ceiling lapse,” Manchin said, according to CNN reporter Manu Raju, who tweeted the senator’s comments.

‘PREVENTABLE CRISIS,’ MCCONNELL SAYS

Calling default a “preventable crisis,” McConnell remained adamant. “Democrats need to tackle the debt limit,” he said on the Senate floor.
