(CNN) Broadcaster and conspiracy theorist Alex Jones said it was a "form of psychosis" that caused him to believe certain events --- like the Sandy Hook massacre -- were staged.

On December 14, 2012, 20 children and six adults were killed by 20-year-old Adam Lanza in Sandy Hook Elementary School in Newtown, Connecticut.

Jones, who founded InfoWars.com and hosted a three-hour news-talk radio program which he said was carried on more than 160 stations, had repeatedly suggested in the past that the Sandy Hook shooting was a "giant hoax" carried out by crisis actors on behalf of people who oppose the Second Amendment.

InfoWars has also suggested the September 11 attacks were an inside job orchestrated by the US government.

This week, Jones acknowledged the shooting was real during a sworn deposition he made as part of a defamation case brought against him by Sandy Hook victims' families.
