Hasson was an aircraft mechanic with the Marine Corps in the first Gulf War, and later went on to serve in the Virginia National Guard before joining the Coast Guard in 1996.
In the months leading up to his arrest last year, Hasson was stationed at Coast Guard headquarters in Washington.
During this time he amassed the weapons in his apartment in Silver Spring. His arsenal included six handguns, seven rifles, two shotguns, more than 1,000 rounds of ammunition, knives, smoke grenades and tactical gear.
The former lieutenant from Silver Spring was inspired by racist mass murderers, including Anders Breivik, and “intended to exact retribution on minorities and those he considered traitors”.
According to the FBI, he also had 30 vials of a human growth hormone – a steroid that “increase ability to conduct attacks”.
Officials said Christopher Hasson, 50, was planning to target liberal politicians and news broadcasters.
this was the domestic terrorism, but US law does not classify this as a distinct offence without an attack being carried out. Hasson pleaded guilty to firearms and drugs charges.
When he was arrested last February, officers found a cache of 15 firearms – which, as a drug user, Hasson was banned from owning – and two illegal gun silencers. He was also in possession of the narcotic Tramadol without a prescription.
Before and during his sentencing hearing, attorneys sparred on whether or not Hasson would have gone on to commit mass murder.
He created an Excel spreadsheet with a list of targets, which included 12 prominent Democrats in Congress and a number of CNN and MSNBC journalists.
US Federal Attorney Robert Hur added that if he hadn’t been arrested when he was, “we now would be counting bodies of the defendant’s victims instead of years of the defendant’s prison time”.
Hasson’s lawyers, however, argued that prosecutors had overstated the threat he posed.
