In his $400 million defamation lawsuit against CBS Corp., Virginia Lt. Gov. Justin Fairfax not only accuses the television network of smearing his name and helping to cost him his partnership at Morrison & Foerster. He also asserts that a senior in-house CBS lawyer, whom he describes as a “friend,” knew the network was airing allegedly false sexual assault claims against him.

CBS has vowed to contest the suit, stating it stands by its coverage of allegations against Fairfax that were made last year by Meredith Watson and Vanessa Tyson.
