Geraldo Rivera has become one of the first Fox News personalities to criticize Tucker Carlson following his abrupt departure from the network this week, citing his "perverse January 6 conspiracy theory" as "bullshit". The exact reason for Carlson's departure remains unclear, although offensive private messages may have played a part. Rivera's criticism is a reminder of the controversy surrounding Carlson's peddling of false information, and it remains to be seen how other Fox News personalities will respond.
