Delaware Superior Court Judge Eric Davis has ruled that Fox Corporation executives Rupert and Lachlan Murdoch must testify in the upcoming defamation trial against Fox News, which is being brought by Dominion Voting Systems. The trial is scheduled to begin on May 24th and could have major implications for Fox News and its parent company, Fox Corporation. It is also a major test of the power of the Murdochs, who have long been seen as untouchable in the media industry.
