A US Coast Guard lieutenant and self-proclaimed white-nationalist with a small arsenal plotted to kill a slew of journalists and democrats — including Sen. Chuck Schumer, Freshman New York Rep. Alexandria Ocasio-Cortez and House Speaker Nancy Pelosi.

Christopher Paul Hasson, 49, was arrested Feb. 15 on gun and drug charges, when authorities found 15 firearms in his Silver Springs, Maryland, home, but prosecutors said those accusations are just the “tip of the iceberg” in documents filed Tuesday in Maryland federal court.

“The defendant intends to murder innocent civilians on a scale rarely seen in this country,” the document arguing for Hasson’s detention pending trial reads.

Though court documents don’t include a specific planned date for the attack, the government said Hasson had been amassing a huge cache of weapons since at least 2017 and began the process of targeting specific victims, including current and former elected officials.

He allegedly compiled an Excel list Jan. 19 of left-leaning senators and media personalities with MSNBC and CNN, including Chris Hayes, “Joey,” thought to be Joe Scarborough, Van Jones and Chris Cuomo.

That same day, some of his Internet searches included, “best place in dc to see congress people,” “where in dc to [SIC] congress live,” “what if trump illegally impeached” and “are supreme court justices protected.”

Prosecutors say Hasson, 49, studied a 1,500-page manifesto left behind by Norwegian terrorist Anders Behring Breivik, the far-right assailant who killed 77 people in Norway in 2011.

The parts Hasson perused, “instruct a prospective assailant to amass appropriate firearms, food, disguises, and survival supplies,” the court documents read.

He also allegedly began taking steroids and narcotics to “increase his ability to conduct attacks.”

When agents searched his cramped basement apartment they found over thirty bottles labeled HGH, or human growth hormone. They also discovered at least 100 pills that appeared to be the painkiller Tramadol and 15 firearms, including several long guns and rifles, and 1,000 rounds of ammunition.

Over the last two years, Hasson made nearly two dozen purchases of firearms or equipment.

Prosecutors say Hasson, who served in the US Marine Corps from 1988 to 1993 and then spent two years on active duty in the Army National Guard, had long-held extremist views.

In a draft email dated June 2, 2017 he wrote “I am dreaming of a way to kill almost every last person on the earth. I think a plague would be most successful but how do I acquire the needed/ Spanish flu, botulism, anthrax not sure yet but will find something,” the court documents say.

In another letter from Sept. 2017 to an American neo-Nazi leader he identified himself as a White Nationalist for over 30 years.

“We need a white homeland as Europe seems lost. How long we can hold out there and prevent n—-ion of the Northwest until whites wake up on their own or are forcibly made to make a decision whether to roll over and die or to stand up remains to be seen,” he allegedly wrote.

Hasson, was assigned to the US coast guard headquarters in DC, when he was arrested Feb. 15 on charges of possession of firearm and ammunition and possession of Tramadol.

” An Active Duty Coast Guard member, stationed at Coast Guard Headquarters in Washington, DC, was arrested last week on illegal weapons and drug charges as a result of an ongoing investigation led by the Coast Guard Investigative Service, in cooperation with the FBI and Department of Justice,” the Coast Guard said in a statement, adding that they couldn’t comment further because this is an open investigation.

It’s unclear what prompted authorities to investigate Hasson.

He’s scheduled to appear for a detention hearing in federal court in Greenbelt Thursday.
