Fox News was sued for defamation Wednesday by Trump supporter Ray Epps, who alleges the network and host Tucker Carlson spread a "fantastical story" about him.
Driving the news: Epps, who emerged at the center of right-wing conspiracy theories after he participated in the Jan. 6 Capitol riot, accuses Fox News and Carlson in his lawsuit of "spreading falsehoods" that he was an undercover FBI agent and was responsible for inciting the riot.
