Fox News and Rupert Murdoch face legal challenges over credibility and dual roles.

Attorneys defending Fox in a defamation case related to false claims about the 2020 election withheld critical information about the role company founder Rupert Murdoch played at Fox News, a revelation that angered the judge when it came up at a Tuesday hearing. Dominion Voting Systems is suing Fox for $1.6 billion, saying it damaged its reputation by repeatedly airing false claims that the company helped orchestrate a fraud that cost former President Donald Trump re-election. The role of Fox executives is at the heart of the case.
