NEW YORK — Prosecutors rested their case against former president Donald Trump on Monday, a momentous day in the month-long trial that was quickly overshadowed by the judge’s angry dressing-down of a witness he thought was being disrespectful.

For most of the day, the trial seemed to be winding down; defense lawyers indicated they did not plan to call Trump as a witness, and might finish presenting their case in a few hours. That schedule suddenly changed when their second witness, lawyer Robert Costello, infuriated the judge.
