Complaints about the ongoing government shutdown escalated this week, putting more pressure on Congress to end the impasse over President Trump’s demand for border wall money, and reopen the government.

On Tuesday, the Administrative Office of the U.S. Courts released a statement that said federal courts would run out of money on Feb. 1, and would have to make decisions on which staff to keep on to work without pay to support “mission critical work.” That would add to the hundreds of thousands of workers who have already been stuck without a paycheck, including those who have been told they are required to keep working.
