The federal government could shut down this weekend after the House rejected President-elect Donald Trump’s plan to fund operations and suspend the debt ceiling, with Democrats and dozens of Republicans refusing to accommodate his demands.

The 235-174 vote Thursday night shooting down the latest deal came after Trump ordered Republican lawmakers to oppose a bipartisan spending agreement lawmakers had reached earlier this week.

Congress has a Friday night deadline to reach a new agreement or risk a partial shutdown that would cut off funding to a range of government operations and personnel.

Here’s how Maine could be affected, based on what followed during shutdowns in 2013 and 2018, and the projected impacts of a shutdown that was discussed during a budget impasse in 2023.

More than 11,000 federal workers in Maine could be furloughed or expected to work without pay during a shutdown.

Essential workers, such as air traffic controllers, Transportation Security Administration screeners and members of the military, would be required to work, but would not be paid for that work until a budget deal is reached and federal operations are funded.

As a result, air travel would not be disrupted and national security work would continue — as long as essential workers continue to work without pay. However, travelers could see longer wait times or delays if the shutdown reaches a point where employees either will not or cannot continue to work without pay.

Acadia National Park would likely close its gates, along with other national parks and monuments. In 2013, the National Park Service turned away millions of visitors to more than 400 parks, monuments, and other sites, leading to a loss of more than $500 million in visitor spending nationwide, according to the Committee for a Responsible Federal Budget, a non-profit dedicated to educating the public on issues of significant fiscal impact.

Many parks remained open during the 2018-2019 shutdown, though no visitor services were provided, and damage and trash build-up were reported at many sites, according to the committee.

Last September, as a shutdown loomed, it was announced that all national parks would close.

The National Park Service’s press team said in an email Thursday that the agency remains hopeful that a lapse in government funding will not occur.

If it does, routine visitor services will be available through Sunday. The park service is continuing to review contingency plans and specifics for individual parks.

Food assistance programs could be affected, especially if a shutdown drags on. 

During last year’s threat of a government shutdown, the White House warned that it could jeopardize nutritional assistance for 7 million women and children nationwide who are helped by the Special Supplemental Nutritional Program for Women, Infants and Children, or WIC.

The Maine Department of Health and Human Services is expecting WIC to be unaffected this time, but department spokesperson Lindsay Hammes said the length of the shutdown could have adverse affects for the program if a shutdown drags on.

The department also expects the Supplemental Nutrition Assistance Program, or SNAP, to be unaffected through the end of the year. “We are working to assess potential impacts for current participants and new enrollees should the federal government be shut down in the new year,” Hammes said in an email.

As of November, 183,711 people in Maine were participating in SNAP and 18,775 were enrolled in the WIC program.

Access to some federal programs, including applications for small business loans and federally backed home mortgages would come to a halt. Funding for federal housing assistance programs, such as Housing Choice Vouchers, may also be jeopardized in a prolonged shutdown.

Social Security benefits would continue so recipients would not feel a disruption in benefit checks. The Social Security Administration would provide limited services like issuing Social Security cards and holding appointments for benefit applications, however.

The SSA would stop services like benefits verifications and processing overpayments, and customer wait times would dramatically increase, according to a shutdown Q&A from Rep. Chellie Pingree’s office.

Mail delivery would be unaffected because the U.S. Postal Service does not depend on Congress for funding.

Federal courts, including in Portland and Bangor, would likely remain open for a few weeks into a shutdown since the court system has additional sources of revenue, such as fees it collects.

Federal courts in Maine have been told they probably have enough funding to stay open for at least three weeks, through Jan. 10, if a shutdown happens, according to the clerk’s office in the U.S. District Court for the District of Maine.

Border crossings would still be staffed and Border Patrol and the Coast Guard would continue to operate.

Some state and local government programs could be affected.

The state funds most of its employees through general funds or non-federal dollars, which means most state government operations would remain unchanged on a day-to-day basis.

A shutdown would impact funding from some federal departments and agencies, but which departments are impacted remains to be seen, based on the actions of Congress, said Sharon Huntley, director of communications for the Maine Department of Administrative and Financial Services.

There are about 2,500 state employees who are funded either entirely or in part by federal agencies, Huntley said in an email.

“For many — if not most — of these employees, their day-to-day will be unaffected for the time being because their department or agency has sufficient funding from existing federal spending authority or alternative funding sources for now,” Huntley said.

She said the state is awaiting guidance from the federal government about which streams of funding would be disrupted by a shutdown.
