Tucker Carlson's departure reveals Fox News' vulnerability.

Tucker Carlson was ousted from Fox News in part due to his private text messages, which were included in public court documents as part of Dominion Voting Systems' defamation lawsuit against the network. The messages showed Carlson disparaging Fox leadership and worrying about how fact-checking former President Trump's false claims about voter fraud would anger the network's audience. The explicit content of the messages became known internally to senior Fox management and played a role in his ouster. Carlson has not commented publicly on his departure from Fox.
