The FBI says it’s focusing on far-right militia groups as it continues to arrest leaders of the January 6 insurrection at the Capitol.

In Texas, federal prosecutors say rioter Guy Reffitt threatened to murder his wife and children if they turned him in — allegedly telling his family, “Traitors get shot.” Reffit is a member of the far-right Three Percenters militia group.

Federal agents have also arrested Bryan Betancur, a self-professed white supremacist who was wearing a GPS ankle bracelet as a condition of his probation on a prior burglary charge. Betancur was photographed at the January 6 riots posing with a Confederate battle flag.

On Monday, the FBI arrested Riley June Williams of Pennsylvania, charging her with stealing a laptop from the office of House Speaker Nancy Pelosi. An FBI complaint accuses Williams of seeking to send the laptop to Russia’s Foreign Intelligence Service.
