Three law firms have indicated they’re investigating Fox Corp.—owner of the Fox News network—for potential shareholder claims related to statements made about voting machine companies broadcast as part of coverage of the 2020 presidential election.

The Kehoe Law Firm, Scott+Scott and most recently Robbins have all announced they’re ready to be contacted by Fox shareholders, implying there may eventually be class action litigation alleging the company’s management breached its fiduciary duties or violated securities laws.
