The last US government shutdown occurred from December 22, 2018, to January 25, 2019, lasting 35 days. It was the longest shutdown in U.S. history and happened due to a funding impasse over President Trump's demand for $5.7 billion for a border wall on the U.S.-Mexico border. About 800,000 federal employees were affected, with many furloughed or required to work without pay, and the shutdown had significant economic impacts.
