A suspect is being held in connection with what’s described as a large-scale terrorist plot targeting Democratic politicians along with journalists working for CNN and MSNBC.

Christopher Paul Hasson, 49, of Silver Spring, Md., a Coast Guard lieutenant, was arrested Friday on gun and drug charges following an investigation in which the Coast Guard and the FBI took part. He is alleged to be a white supremacist who was planning to conduct a mass killing.

“Hasson’s case was first circulated by counterterrorism expert Seamus Hughes and the George Washington Program on Extremism,” CNN reports. “Hasson’s hit list includes Democratic politicians — Rep. Alexandria Ocasio-Cortez, of New York, Sens. Chuck Schumer of New York, Cory Booker of New Jersey, Richard Blumenthal of Connecticut and Kamala Harris of California, as well as former Rep. Beto O’Rourke of Texas — as well as CNN journalists Don Lemon, Chris Cuomo and Van Jones and MSNBC’s Chris Hayes, Ari Melber and Joe Scarborough.”

Hasson was said to be inspired by the manifesto of Anders Breivik, a Norwegian who was convicted in 2011 of two terror attacks that killed 77 people, CNN notes.

“The government says Hasson also stockpiled steroids and human growth hormone ‘to increase his ability to conduct attacks,’ consistent with the directions in Breivik’s manifesto,” the report adds.

The report quotes documents from prosecutors saying: “The defendant is a domestic terrorist, bent on committing acts dangerous to human life that are intended to affect governmental conduct.”

A draft email by Hasson that was acquired by prosecutors reportedly says: “I am dreaming of a way to kill almost every last person on the earth.”

Hasson was scheduled to appear in court today.
