In the past, it was common for US government services to close their doors. This has happened about ten times since 1980. The longest lasted 35 days and occurred in the winter of 2018/2019.
Correction: An earlier version of this article said a shutdown was threatened by the debt ceiling. this is not true. It’s about reaching an agreement on the budget.
