When the House select committee investigating the Capitol riot held its first prime-time hearing two weeks ago, Fox News pointedly chose not to air it. But not only did it not air the committee hearing, it hosted Tucker Carlson’s opinion show at the same time, during which Carlson promoted misinformation about what had occurred on Jan. 6, 2021. Among his guests that evening, for example, was Darren Beattie, a former Trump administration official who promoted long-debunked or otherwise unsupported allegations about the involvement of federal agents in the riot.
