Friday was the 35th and last day of the government shutdown after President Trump agreed to a plan to reopen the government.

The shutdown is affecting about 800,000 federal employees—many of whom live paycheck-to-paycheck—and services for millions of people in the public. The longer it lasts, the more its effects are felt.
