WASHINGTON (AP) — President Donald Trump’s law-enforcement intervention in the nation’s capital has led to federal charges against more than 50 people over the past month. A frustrated judge says prosecutors already have dropped charges in at least 11 of those cases. U.S. Magistrate Judge Matthew Sharbaugh expressed concern on Tuesday that the flurry of dismissed cases is wasting the district court’s resources. He questioned whether Justice Department prosecutors are making charging decisions before cases are properly investigated and vetted. Trump claims his emergency 30-day deployment of federal agents and National Guard members is making the streets safer for District of Columbia residents.
