Trump has also threatened to deploy the National Guard as part of a crackdown on what he falsely says is rising crime in Washington.
Violent crime in the capital fell in the first half of 2025 by 26% compared with a year earlier, police statistics show.

Trump’s threat to send in the National Guard comes weeks after he deployed California’s military reserve force into Los Angeles to quell protests over immigration raids, despite objections from local leaders and law enforcement.
The President has frequently mused about using the military to control America’s cities, many of which are under Democratic control and hostile to his nationalist impulses.
