Government shutdown deadlines — and even full-on shutdowns — aren’t new for Washington, but this time, with federal funding set to run out Saturday after midnight, no one knows quite what to expect.

The plans for an impending reduction come after a federal judge on Thursday ordered multiple agencies to reinstate thousands of probationary employees.

The Senate finds itself on Friday in a familiar position, working to avoid a partial government shutdown with just hours to spare as Democrats confront two painful options: allowing passage of a bill they believe gives President Donald Trump vast discretion on spending decisions or voting no and letting a funding lapse ensue.
