President Joe Biden urged Republicans to “get out of the way” and let Democrats suspend the nation’s debt limit, hoping to keep the U.S. government from bumping dangerously close to a credit default as Senate Republican leader Mitch McConnell refuses to lend his party’s help.

Biden’s criticism on Monday came with Congress facing an Oct 18 deadline to allow for more borrowing to keep the government operating after having accrued a total public debt of $28.4 trillion.

The House has passed a measure to suspend the debt limit, but McConnell is forcing Senate Democrats into a cumbersome process that could drag on and approach the deadline with little margin for error.

Both Biden and McConnell have promised that the country will avoid default, yet the public fight and political posturing risks an economic meltdown. The global economy relies on the stability of U.S. Treasury notes, and unpaid debt could crush financial markets and hurl America into recession.

Biden noted that the debt limit applies to borrowing that has already occurred, including under former President Donald Trump, and said Republicans are hurting the country by blocking the limit’s suspension.

“They need to stop playing Russian roulette with the U.S. economy,” Biden said at the White House. “Republicans just have to let us do our job. Just get out of the way. If you don’t want to help save the country, get out of the way so you don’t destroy it.”

Unmoved, McConnell said Republicans had given the Democrats a roadmap for dealing with the debt ceiling with months of warning. “I suggest that our Democratic colleagues get moving,” McConnell said at the Capitol.

Once a routine vote, raising the nation’s debt limit has become increasingly partisan. It’s become a favorite political weapon of Republicans to either demand concessions or force Democrats into unpopular votes to enable more borrowing.

McConnell has tied the vote to Biden’s multitrillion-dollar tax and economic agenda that awaits Congressional approval. But Biden says the price tag in terms of debt for his plan will be “zero,” paid for by raising taxes on corporations and on the wealthy, whom the House Democrats have defined as individuals earning more than $400,000 a year, or couples making more than $450,000.
