Arizona shooting victim James Eric Fuller remains under psychiatric observation following his arrest Saturday for threatening a Tea Party leader at a town hall meeting.

Fuller’s arrest follows his public rebuking of Sarah Palin and Glenn Beck for inciting gunman Jared Loughner and claiming that Fox News promotes war the day before his arrest.

Pima County Sheriff spokesman Jason Ogan told FoxNews.com that Fuller -- who was charged with disorderly conduct and making threats -- is still at an undisclosed facility in Tucson, Ariz.

On Friday, Media Matters touted their interview with Fuller, who said Palin and other media figures had “definitely” had an impact on the Tucson shooting. He also said Palin “should be incarcerated for treason for advocating assassinating public officials.”

In the interview Fuller, when asked if he had been would appear on Fox News, he said said that he wasn't approached and even if he would be, he'd decline because he'd be afraid it "might develop into a screaming session because I think they promote the war."

"I would stand up and just scream 'whores' at them, with my leg bleeding, and shock and with the congress lady laying on the pavement after having a slug pass through her head," Fuller said in the interview. "I know they're just going to attack, they would probably attack me," he said. "I am willing to take them on. I want to call them out and see if they have a peep to say."

The news program "Democracy Now" also featured an interview with Fuller, who said that after being hospitalized for his wounds, he stayed up most of the night, writing down the words Declaration of Independence to help him try to calm down.  The 63-year-old disabled veteran was shot in the knee and back in the shooting rampage that left six dead and 13 injured -- including Rep. Gabrielle Giffords -- at a Tucson supermarket.

But on Saturday Fuller appeared to become enraged and allegedly started threatening Tucson Tea Party co-founder Trent Humphries at a town hall meeting being taped for an ABC News special.

Fuller -- who was sitting in the front row -- allegedly became agitated when Humphries suggested postponing gun control conversations until after all six shooting victims had been buried.

Ogan said that Fuller snapped a photo of the Tea Party leader and yelled out, "You're dead." Fuller also began ranting, and as he was being escorted out, he addressed the audience as "whores," according to Ogan.

Fuller was involuntarily committed for psychiatric evaluation and was expected to be kept for 72 hours for observation.
