Trump taunted Gov. Jay Inslee and Mayor Jenny Durkan about the situation on Twitter and said the city had been taken over by "anarchists."
"Take back your city NOW. If you don't do it, I will," Trump tweeted.
Radical Left Governor @JayInslee and the Mayor of Seattle are being taunted and played at a level that our great Country has never seen before. Take back your city NOW. If you don’t do it, I will. This is not a game. These ugly Anarchists must be stooped IMMEDIATELY. MOVE FAST!— Donald J. Trump (@realDonaldTrump) June 11, 2020
The "Capitol Hill Autonomous Zone" sprung up after police on Monday removed barricades near the East Precinct and basically abandoned the structure after officers used tear gas, pepper spray and flash bangs over the weekend to disperse demonstrators they said were assaulting them with projectiles.
The president has sparred with the liberal Northwest Democrats before, especially Inslee, who previously sought his party's presidential nomination.
Inslee tweeted Thursday that state officials will not allow threats of military violence from the White House.
"The U.S. military serves to protect Americans, not the fragility of an insecure president," Inslee tweeted.
What we will not allow are threats of military violence against Washingtonians coming from the White House.— Governor Jay Inslee (@GovInslee) June 11, 2020
The U.S. military serves to protect Americans, not the fragility of an insecure president.
The zone set up by protesters stretches across several blocks on Capitol Hill, where dozens of people show up to listen to speakers calling for police reform, racial justice and compensation for Native groups on whose land the city of Seattle was founded.
Signs proclaim "You are entering free Capitol Hill" and "No cop co-op" along sidewalks where people sell water and other wares.
"From what I've gathered, we're trying to take our community back so we can live without a massive police force patrolling the streets," Michael Taylor told The Seattle Times.

Over the weekend, police were sharply criticized by City Council members and other elected leaders. Since officers dialed back their tactics, the demonstrations have largely been peaceful.
Police officials say they are looking to reopen the precinct. At a news conference Wednesday, Assistant Chief Deanna Nollette said the barriers were removed from the front of the building after it became a flashpoint between officers and protesters.
Nollette said the precinct has been boarded up because of credible threats that it would be vandalized or burned. She offered no details about the threats and no fires have been reported at the site.
She said protesters have set up their own barricades, which are intimidating some residents.
"We are dedicated to working with peaceful protesters on a way to move forward," Nollette said.
Protesters have said they want to see the precinct turned into a community center or used for purposes other than law enforcement.
