Those are among the many consequences of a government shutdown if an interim spending bill is not enacted by the end of Friday. Congressional leaders scrambled this week to avert a looming partial shutdown of the federal government. In the event of a partial shutdown, federal agencies will discontinue all “nonessential” discretionary functions, while “essential services” will continue. National parks and monuments closed during the 2013 shutdown, but many remained open during the 2018-2019 shutdown, although no visitor services were available, and the National Park Service reported damage and trash accumulation at sites across the country. Shutdowns often briefly affect the stock market as well, with investors balking at the prospect of a shutdown but recovering shortly after a shutdown is resolved.
