2018–2019 United States federal government shutdown
At midnight EST on Saturday, December 22, 2018, the Federal government of the United States began a shutdown because neither legislative funding was passed for the upcoming fiscal year or a continuing resolution. It lasted until 25 January 2019, the longest shutdown in history. This was also a response from President Donald Trump’s refusal to sign a bill to keep the government open due to lack of funding for his border wall. The shutdown could cost billions of dollars.
