The White House increased the presence of federal law enforcement in Washington over the weekend, deploying 450 officers across all four quadrants of the city Saturday and on Sunday in high-traffic areas, as Trump has ramped up threats of taking control of D.C. and its local police force.

President Donald Trump will hold a news conference Monday that he said "will, essentially, stop violent crime in Washington, D.C." The president promoted the news conference in multiple posts on his social media platform and on Sunday posted that it would "also be about Cleanliness and the General Physical Renovation and Condition of our once beautiful and well maintained Capital.

The FBI agents, primarily from the Washington Field Office, will work overnight shifts for at least one week supporting D.C. police.
