I'm talking here about the part of the government that governs, not the nuts and bolts part that does stuff like enforcing the laws and regulating the airlines and banks and issuing passports and helping people if and when they suffer the ravages of hurricanes or even manmade disasters which can include forest fires. The administrative part of the government has been shut down repeatedly in recent years — in 2013 over the Affordable Care Act, in 2018 over immigration, and again in 2018 over funding the wall. That shutdown lasted 35 days and continued into the new Congress seated on Jan. 3, 2019.
See what I mean about those shutdowns? The Congress caused them, because the Congress was in session for all three of them and had disagreements over the budget and whether it would include money for things either Republicans or Democrats didn't want funded.
