While many federal agencies have been scaled back or completely stopped doing business because of the government shutdown, some agencies are still open for business.

President Donald Trump told Congress that he would not sign a stop-gap funding measure unless it included funds for a southern border between the United States and Mexico. Since the measure didn’t include funds for a wall, the third government shutdown of 2018 began at 12:01 a.m. Dec. 22. The president has taken to Twitter since the shutdown to indicate that he will not compromise.
