WASHINGTON - As the Senate marches ahead with a bipartisan approach to prevent a government shutdown, House Speaker Kevin McCarthy is back to square one — asking his hard-right Republicans to do what they have said they would never do: Approve their own temporary House measure to keep the government open.

The Republican speaker laid out his strategy Wednesday behind closed doors, urging his unruly Republican majority to work together. He set up a test vote for Friday, one day before Saturday’s shutdown deadline, on a far-right bill. It would slash federal spending by 8% from many agencies and toughen border security but has been rejected by President Biden, Democrats and his own right-flank Republicans.

“I want to solve the problem,” Speaker McCarthy told reporters afterward at the Capitol.

But pressed on how he would pass a partisan Republican spending plan that even his own right flank doesn’t want,

Speaker McCarthy had few answers. He rejected outright the Senate’s bipartisan bill, which would fund the government to Nov. 17, adding $6 billion for Ukraine and $6 billion for U.S. disaster relief while talks continue. Instead, he insisted, as he often does, that he would never quit trying.

Congress is at a crossroads days before a disruptive federal shutdown that would halt paychecks for millions of federal workers, leave 2 million active duty military troops and reservists to work without pay, close down many federal offices, and leave Americans who rely on the government in ways large and small in the lurch.

President Biden in California at a meeting of the President’s Council of Advisors on Science and Technology said Wednesday he didn’t think a federal shutdown was inevitable.

“I don’t think anything is inevitable when it comes to politics,” President Biden said.

But when asked what could be done to avoid it, the president said: “If I knew that I would have done it already.”

As the Senate pushes ahead in bipartisan fashion, Speaker McCarthy is demanding President Biden meet to discuss border security measures. But the beleaguered speaker has little leverage left with the White House without the power of his House majority behind him and after he walked away from the debt deal he and President Biden reached earlier this year that is now law.

On the other side of the Capitol, Senate Majority Leader Chuck Schumer opened the chamber warning of the right-wing extremes that “seem to exult in shutting down government.”

The Senate Republican leader Mitch McConnell was in rare agreement with the Democratic leader, urging his House colleagues to consider the Senate’s stopgap approach and move off the shutdown strategy.

“We can take the standard approach and fund the government for six weeks at the current rate of operations or we can shut the government down in exchange for zero meaningful progress on policy,” Sen. McConnell said.

Sen. McConnell said he, too, would like to do something about the “Democrats’ reckless spending” and boost border security. But he said, “these important discussions cannot progress” if the functions of government “end up being taken hostage.”

When Sen. McConnell mentioned a vote against the bill would mean voting against pay for border patrol agents and others, it sparked a response from President Biden on social media.

“You know, I agree with Mitch here. Why the House Republicans would want to defund Border Patrol is beyond me,” President Biden wrote.

With the Senate expected to spend the rest of this week working to pass its bill over the objections of Sen. Rand Paul, R-Ky., and others on the right flank who want to halt aid to Ukraine and push for steeper spending cuts, all action in Congress is crushing toward a last minute deadline.

The federal government would begin to shut down if funding is not secured by Sunday, Oct. 1, the start of the new fiscal year. A new economic assessment from Goldman Sachs estimated a federal shutdown would subtract 0.2 percentage points from fourth quarter GDP growth each week it continues, according to a report issued Wednesday.
