Judge scolds Fox News and Rupert Murdoch over withheld evidence and dual roles.

The judge overseeing Dominion Voting Systems' defamation case against Fox News plans to appoint a special master to investigate whether the network lied to the court to withhold key evidence. The move comes after Fox's attorneys were accused of making misrepresentations to the court. The special master will investigate what sanctions might be appropriate against Fox, including potentially instructing jurors in the case that Fox inappropriately blocked Dominion from obtaining key evidence. Fox denies wrongdoing and says it properly disclosed Murdoch's roles in its public financial filings.
