Christopher Hasson, the Coast Guard lieutenant called a “domestic terrorist” by the U.S. government, pleaded not guilty in court Monday.

Hasson, 49, has been charged with unlawful possession of silencers, possession of firearms by a drug addict and unlawful user and possession of a controlled substance and faces up to 21 years in prison if convicted.

He has not yet been indicted on any terrorism-related charges, but those are expected.

Prosecutors previously called the current charges “just the tip of the iceberg.”

Hasson was arrested in late February for what officials called “the proverbial tip of the iceberg” after he allegedly stockpiled weapons, ammunition and a target list of Democratic politicians and journalists.

“The defendant intends to murder innocent civilians on a scale rarely seen in this country,” the government said in the filing at the time.

Law enforcement officials found 15 firearms and more than 1,000 rounds of ammunition at his Silver Spring, Maryland, apartment earlier this month, along with a list of “prominent Democratic Congressional leaders, activists, political organizations, and MSNBC and CNN media personalities,” including Sens. Tim Kaine, Chuck Schumer, Elizabeth Warren, Kirsten Gillibrand, Cory Booker and Kamala Harris, as well as Rep. Maxine Waters, former Rep. Beto O'Rourke, CNN hosts Chris Cuomo, Van Jones and Don Lemon, MSNBC host Chris Hayes and former Hillary Clinton campaign chairman John Podesta.

Thomas Patrick Windom, representing the prosecution, said he plans to provide more evidence to the court this week, according to ABC.
