Trump predicts little progress in potential shutdown talks with 'crazy' Schumer, Jeffries

And there is a brewing tension between Republicans and Democrats over just how the looming government funding fight will shake out.

"But it's almost a waste of time to meet, because they never approve anything," Trump added.

"I don't believe anybody is capable of making a deal with these people," he continued. "They have gone crazy."

Fox News Digital reached out to Schumer and Jeffries for comment but did not immediately hear back.

The top Democrat in the Senate did, however, react to Trump's sentiment on X. 

"President Trump calls it a 'waste of time' to meet - I call it a waste of leadership for Trump to have no plan to lower costs for hardworking Americans, or stop cuts to health care, veterans, and Social Security," he said. 

Lawmakers must pass the dozen spending bills needed to fund the government to avert a partial shutdown, but that process, known as regular order, has not happened in decades.

However, any CR must pass muster with Senate Democrats, given that the legislation has to pass through the upper chamber's 60-vote threshold.

Ahead of the vote to pass three spending bills in the Senate, which included funding for military construction and Veterans Affairs, agriculture and the Food and Drug Administration (FDA), and the legislative branch, congressional Democrats vowed that they would play ball - as long as the appropriations process was bipartisan.

"We all want to pursue a bipartisan, bicameral appropriations process," Schumer said at the time. "That's how it's always been done, successfully, and we believe that, however, the Republicans are making it extremely difficult to do that."

Earlier this year, Schumer briefly flirted with a government shutdown. However, he eventually relented and voted with Republicans to keep the lights on in Washington, and in the process ignited a firestorm within his own party over his ability as leader of the Senate Democratic caucus.
