The District of Columbia is not a state. The president can call up US troops for use in D.C. he does not need the Insurrection Act in D.C, to the best of my knowledge.
Doesn’t make it right, but might make it legal...

A massive series of barricades has gone up around the White House. Guard troops from as far away as Utah are patrolling our streets, keeping peaceful protesters far from Trump. Military helicopters fly over the city round-the-clock. More than 1,000
federal police officers, many without badges or insignia to show what agency they work for, have been sent to the District from around the country. Active-duty Army soldiers were flown in and stand ready to help Trump disrespect a city that’s
46 percent black.
Trump has free rein in D.C. because of the city’s unique constitutional status. We only have “home rule,” granted by Congress, not sovereignty; we have no governor, so the D.C. National Guard answers to Trump, not to Mayor Muriel E. Bowser. D.C. residents pay federal taxes, but we have only shadow senators and a nonvoting delegate to the U.S. House. We have the trappings of independence but none of the benefits of control: It’s a burlesque of government when federal authorities want to toy with us.

Well, I need to research this a bit more, because it does say here that Trump came very close to using the Insurrection Act to call in active troops to Washington:
