President Donald Trump has deployed the National Guard to Washington DC and taken control of the city's police force as he pledges to crack down on crime and homelessness in the nation's capital.

Trump declared a "public safety emergency" on Monday, deploying 800 National Guard troops who will bolster hundreds of federal law enforcement officers who were deployed over the weekend.

"It's becoming a situation of complete and total lawlessness," he told reporters at the White House.

The city's Mayor Muriel Bowser has rejected the president's claims about crime and while there was a spike in 2023, statistics show it has fallen since then. Violent crime in the city is also at a 30-year low.

"I'm announcing a historic action to rescue our nation's capital from crime, bloodshed, bedlam and squalor and worse," Trump said during a news conference in which he was flanked by US Attorney General Pam Bondi, who will lead the city's police force while it is under federal control.
