Washington, D.C. Attorney General Karl Racine filed a lawsuit on Tuesday (Dec. 14) against the Proud Boys and the Oath Keepers over the Jan. 6 U.S. Capitol attack. The suit accuses the two far-right groups of conspiring to overturn the 2020 presidential election results with a “coordinated act of domestic terrorism” and claims they “worked together to plot, publicize, recruit for and finance their planned attack.”

The lawsuit, which was filed in a D.C. federal court, also claimed the Proud Boys and Oath Keepers caused “actual physical financial harm to our city, its employees and our residents.” A.G. Racine is seeking monetary damages from the two groups for the injuries they caused to D.C. police officers and property during the riot.

“I’m suing the Proud Boys and the Oath Keepers, the first civil lawsuit by a government entity against the Jan. 6 insurrectionists,” Racine tweeted on Tuesday. “They caused extensive damage to the District, our democracy and particularly the brave men and women of our Metropolitan Police Department.”

“Today, we’re holding these insurrectionists accountable for conspiring to terrorize the District by planning, promoting and participating in the deadly attack on the Capitol,” he continued. “I’m seeking damages in this case and will keep working to ensure such an assault never happens again.”

Both the Proud Boys and Oath Keepers were previously named in lawsuits filed by lawmakers and Capitol police officers over the deadly Jan. 6. attack. However, Tuesday’s civil suit is the first lawsuit filed against the groups by a state or municipal government agency, Racine said.

The Proud Boys and Oath Keepers are accused of violating the Ku Klux Klan Act of 1871, which allows for civil lawsuits to be filed against those who try to interfere with government proceedings. Racine’s lawsuit also specifically names more than 30 members of the two groups, almost all of whom have already been criminally charged for allegedly participating in the riot.
