Federal prosecutors said that a Coast Guard lieutenant arrested last week is a “domestic terrorist” who intended to kill “prominent Democratic congressional leaders” and “MSNBC and CNN media personalities,” among others.

According to a court filing, Christopher Paul Hasson was arrested Feb. 15 on gun-and-drug-related charges. Prosecutors ask that he be detained pending trial because “the defendant intends to murder innocent civilians on a scale rarely seen in this country.”

Prosecutors say Hasson’s targets included House Speaker Nancy Pelosi, Sens. Chuck Schumer, Kirsten Gillibrand, Elizabeth Warren, Cory Booker and Kamala Harris, Reps. Alexandria Ocasio-Cortez and Maxine Waters, MSNBC hosts Chris Hayes and Joe Scarborough, and CNN hosts Chris Cuomo and Van Jones.

Hasson, the filing says, is an “obvious danger to the community” with a years-long record of expressing extremist views, which were discovered in several emails and email drafts obtained by law enforcement. The filing cites a June 2017 email draft in which Hasson said he was “dreaming of a way to kill almost every last person on the earth,” as well as a September 2017 email Hasson sent to himself “which he apparently wrote to a known American neo-Nazi leader” espousing a desire for a “white homeland.”

The filing also cites Google searches conducted by Hasson for terms including “what if trump [sic] is illegally impeached,” and “where in dc to [sic] congress live.”

Hasson also frequently read a manifesto written by Norwegian white supremacist terrorist Anders Breivik, and appeared to follow Breivik’s instructions for amassing supplies and weapons, according to the filing. Law enforcement agents, prosecutors say, found fifteen firearms and over 1,000 rounds of ammunition and other supplies, including steroids, when executing a search warrant.

According to the filing, Hasson’s hit list was consistent with the kinds of people identified by Breivik as “traitors.”

Hasson is set to appear in court Thursday afternoon. The office of the Federal Public Defender, District of Maryland did not immediately respond to a request for comment from TheWrap.

The court filing was first reported by Seamus Hughes, deputy director of the Program on Extremism at George Washington University.
