An attempt at a panel discussion about fake news on the Moscow-based network RT featuring Horner degenerated into an increasingly weird shouting match as the host struggled unsuccessfully for control.
During the 2016 presidential election, Horner created a list of websites to spread false information.
Horner told The Washington Post previous year that he thought Donald Trump won the presidency because of his fake stories because "his followers don't fact-check anything".
The county's medical examiner found no signs of foul play, Casey said, adding that Horner had a history of prescription drug abuse and that "evidence at the scene suggested this could be an accidental overdose".
The writer gained more notoriety during the 2016 United States presidential race between Donald Trump and Hillary Clinton by claiming, for example, that protesters were being paid thousands of dollars to demonstrate at Donald Trump's campaign rallies. "Anybody who gets tricked by my stuff is people that I'm targeting, trying to make them change the way they think". In one fake story, The Washington Post reports, he claimed that President Obama used his own money to keep open a "federally funded" Muslim culture museum during a government shutdown.
"His followers don't fact-check anything - they'll post everything, believe anything", Horner told the paper about Trump. "I thought I was messing with the campaign, maybe I wasn't messing them up as much as I wanted - but I never thought he'd actually get elected ..." Eventually, Horner turned his back on the camera.
"Honestly, people are definitely dumber".
"I do it to try to educate people", Horner claimed in the interview on CNN.
J.J. Horner, Paul's brother, thought differently of his brother's work, choosing to think of it as well-pointed commentary rather than disinformation. "He left us peacefully in his sleep Monday morning, September 18th, at our mother's house in Laveen", he wrote.
Horner said he was beginning to regret just how popular a phenomenon his fake news stories became given the outcome of the election.
"My sites were picked up by Trump supporters all the time", Horner said.
