WASHINGTON (AP) -- It's become tradition. Congressional leaders from both major political parties blame each other for a potential government shutdown as the budget year draws to a close.

But this year, the posturing is starting extraordinarily early.

The finger-pointing with more than two months to go in the fiscal year indicates the threat of a stoppage is more serious than usual as a Republican-controlled Congress seeks to make good on its policy priorities, often with no support from the other political party.

Democratic leadership from both chambers and the two panels responsible for drafting spending bills met behind closed doors recently to discuss the strategy ahead. The leaders emerged demanding that Republicans work with them but were careful to avoid spelling out red lines if Republicans don't.

"We are for a bipartisan, bicameral bill. That's what always has been done," said Senate Democratic leader Chuck Schumer. "The onus is on the Republicans to help us make that happen."

On the Republican side, lawmakers describe the Democrats as itching for a shutdown. Senate Majority Leader John Thune said Schumer had threatened a shutdown should Republicans pass a bill to roll back $9 billion in public broadcasting and foreign aid funds. Republicans subsequently passed those cuts.

"It was disturbing to see the Democratic leader implicitly threatening to shut down the government in his July 'Dear Colleague' letter, but I'm hopeful that he does not represent the views of Senate Democrats as a whole," Thune said.

The federal government is operating on a full-year continuing resolution that provided about $1.7 trillion in spending for defense and non-defense programs. The funding expires Sept. 30.

President Donald Trump requested a comparable amount for the coming fiscal year, but the Republican proposed dramatically overhauling how that money is distributed to include more for defense and border security and significantly less for health, education, housing and foreign assistance.

So far, the House has approved two of the 12 annual spending bills. The Senate has yet to approve any, but those bills that have advanced out of the Senate Appropriations Committee are enjoying bipartisan support while the House bills are generally advancing out of committee on party line votes.

This week, the Senate is expected to consider the appropriations bill to fund military construction projects and the Department of Veterans Affairs, generally one of the easier spending bills to pass. One or two others could get added to the package.

Congress got off to a late start on the funding process. Republicans prioritized Trump's tax and spending cut bill. Most lawmakers agree Congress will need to pass a stop-gap measure before Sept. 30 to avoid a shutdown and allow lawmakers more time to work on the full-year spending measures.

Democrats overwhelmingly opposed this year's funding bill that expires in two months. But in the end, Schumer and nine Democratic colleagues decided a government shutdown would be even worse. They voted to allow the bill to proceed and overcome a filibuster, giving Republicans the ability to pass it on their own on a final vote.

Schumer took considerable heat from progressives for his strategy. House Democratic leadership issued a statement at the time saying "House Democrats will not be complicit." And members of his own caucus publicly expressed disagreement.

"If we pass this continuing resolution for the next half year, we will own what the president does," said Sen. Adam Schiff, D-Calif. "I am not willing to take ownership of that."

Some liberal groups threatened to hold protests at various events Schumer was planning to promote a new book, and some of those events ended up being postponed due to security concerns.

The Democratic frustrations have only grown stronger in the ensuing months.

First, the Democrats watched the Trump administration slow-walk or block hundreds of billions of dollars from going out in part through the work of its Department of Government Efficiency. Then they watched as Republicans passed Trump's big tax and spending cut bill without any Democratic votes.

Finally, they watched as Republicans this month canceled $9 billion in foreign aid and public broadcasting funds when much of it had been previously agreed to on a bipartisan basis.

Meanwhile, Trump's director of the Office of Management and Budget, Russ Vought, declared that the appropriations process "has to be less bipartisan."

Democrats complain that much of the work taking place in the House has been a waste of time, since those partisan bills have no chance of getting 60 votes in the 100-member Senate.

"At this point in time, why have appropriations if they can just unilaterally through rescissions whack it all away?" said Rep. Mike Quigley, D-Ill. "I think what you're seeing is more frustration than I've ever witnessed."

Republicans control all the levers of power in Washington. That could make it harder to blame Democrats for a shutdown. But in the end, any bill will need some Democratic support to get the 60 votes needed to overcome a filibuster.

"Our concern is that from their standpoint, they want to have a shutdown," Sen. John Hoeven, R-N.D., said of Democrats. "... The Democrats see it as a way to derail the agenda that we're putting through."

Sen. John Barrasso, the No. 2-ranked Republican in the Senate, said Republicans were determined to hold votes on the 12 spending bills. He said that Schumer "had unilaterally shut down the appropriations process" in previous years by not holding such votes, moving instead to negotiate directly with GOP leadership in the House and then-President Joe Biden's Democratic administration on an all-encompassing spending package.

"If Democrats walk away from this process again, simply to protect wasteful Washington spending," Barrasso said, "they will be the ones sabotaging the Senate and shutting down the government."
