Updated 12:35 p.m.: The top Republicans in Congress say they’re heading to the White House Tuesday afternoon to meet with President Donald Trump even though top Democrats have backed out of the meeting.

House Speaker Paul Ryan and Senate Majority Leader Mitch McConnell said in a joint statement that Democrats are “putting government operations, particularly resources for our men and women on the battlefield, at great risk by pulling these antics.”

Ryan and McConnell said that if Democrats want to reach an agreement, they will attend the White House meeting.

The top two Democratic leaders in Congress pulled out of a meeting with President Donald Trump on Tuesday after he said that differences over immigration and tax policy make it unlikely they’d reach a deal to prevent a government shutdown.

“Given that the President doesn’t see a deal between Democrats and the White House, we believe the best path forward is to continue negotiating with our Republican counterparts in Congress instead,” House Minority Leader Nancy Pelosi and Senate Minority Leader Chuck Schumer said in a joint statement.

They said they’d skip a “show meeting” at the White House and instead ask for a meeting with their Republican counterparts, House Speaker Paul Ryan and Senate Majority Leader Mitch McConnell.

Trump sparked the dispute with a tweet preceding a scheduled meeting with congressional leadership Tuesday afternoon.

Meeting with “Chuck and Nancy” today about keeping government open and working. Problem is they want illegal immigrants flooding into our Country unchecked, are weak on Crime and want to substantially RAISE Taxes. I don’t see a deal!

“Meeting with ‘Chuck and Nancy’ today about keeping government open and working,” Trump said on Twitter. “Problem is they want illegal immigrants flooding into our Country unchecked, are weak on Crime and want to substantially RAISE Taxes. I don’t see a deal!”

White House aides didn’t immediately respond to requests to elaborate on Trump’s declaration.

Some Democrats have called for any year-end spending deal to include legislation that would codify an Obama administration policy providing protection against deportation for young undocumented immigrants brought to the country as children. Trump, who announced in September he was ending the program, has said any deal protecting the so-called “Dreamers” should be paired with funding for a border wall and legislation that would reduce legal immigration.

If Democrats and Republicans do not reach a deal on spending by Dec. 8, the federal government could face a partial shutdown.

The Dec. 8 deadline was set in a deal Schumer and Pelosi struck with Trump — against the wishes of Ryan and McConnell — to avoid a government shutdown and debt default in September. They agreed to fund the government at current levels and suspend the debt limit for three months.

Since that deal was struck, Congress has focused mostly on a tax overhaul and has made little progress reaching a spending deal to keep the government open. Other issues have also piled up, including the fate of cost-sharing subsidies that help defray deductibles and coinsurance payments for low-income patients with Obamacare insurance policies. Trump stopped paying the subsidies.

The negotiations also include efforts to lift legislative caps on military spending, raise the debt limit, provide more funding for disaster assistance, and extend a children’s health insurance program and an intelligence surveillance program.

Several of those issues face year-end deadlines and may end up in a huge spending plan that requires votes from both Republicans and Democrats.

The Trump administration does not want to include immigration as part of the year-end spending deal to keep the government open, White House spokeswoman Sarah Huckabee Sanders said on Monday.

“We hope that the Democrats aren’t going to put our service members abroad at risk by trying to hold the government hostage over partisan politics, and attaching that,” Sanders told reporters on Monday.
