While Fox News host Tucker Carlson’s claims that the NSA has been spying on him may sound like his latest effort to lob a conspiracy theory out into the universe to see what sticks, he might not be as off his rocker as the spy agency would have you think. Carlson launched into a diatribe Monday evening accusing the surveillance giant of spying on him and of having plans to boot his show off air—without providing any evidence to that effect. That prompted the NSA to drop a rare statement denying his claims and calling him out for lying Tuesday evening.
