Fox News's Sean Hannity pulled a gun on liberal contributor Juan Williams when the cameras were turned off following a show last year, CNN reports. Three sources tell CNN the incident happened after Hannity and Williams had argued on air. They say Hannity took out a gun and pointed it at Williams, with the light from the gun's laser sight appearing on Williams' body. Hannity, who is licensed to carry, says the gun was unloaded, and he took it out "for educational purposes only." Williams says the incident "is being sensationalized," adding that he never felt in danger. Regardless, the sources say Williams and others present were obviously upset by the incident when it happened. Fox News says it's already looked into the situation. (More Sean Hannity stories.)
