WASHINGTON — Two people who prosecutors say were motivated by white supremacist ideology have been arrested on charges that they used the social media messaging app Telegram to encourage hate crimes and acts of violence against minorities, government officials and critical infrastructure in the United States, the Justice Department said Monday.
The defendants, identified as Dallas Humber and Matthew Allison, face 15 federal counts in the Eastern District of California, including charges that accuse them of soliciting hate crimes and the murder of federal officials, distributing bombmaking instructions and conspiring to provide material support to terrorists.
Humber, 34, of Elk Grove, California, and Allison, 37, of Boise, Idaho were arrested Friday. Humber pleaded not guilty in a Sacramento courtroom Monday to the charges. Her attorney Noa Oren declined to comment on the case Monday afternoon after the arraignment.
It was not immediately clear if Allison had an attorney who could speak on his behalf.
The indictment accuses the two of leading Terrorgram, a network of channels and group chats on Telegram, and of soliciting followers to attack perceived enemies of white people, government buildings, energy facilities and ''high-value'' targets such as politicians.
''Today's action makes clear that the department will hold perpetrators accountable, including those who hide behind computer screens, in seeking to carry out bias-motivated violence,'' Assistant Attorney General Kristen Clarke, the Justice Department's top civil rights official, said at a news conference.
The pair's exhortations to commit violence included statements such as ''Take Action Now'' and ''Do your part,'' and users who carried out acts to further white supremacism were told they could become known as ''Saints,'' prosecutors said.
Justice Department officials say Humber and Allison used the app to transmit bomb-making instructions and to distribute a list of potential targets for assassination — including a federal judge, a senator and a former U.S. attorney — and to celebrate acts or plots from active Terrorgram users.
