The lawsuit was filed in U.S. District Court in Virginia’s Eastern District.

Fairfax has repeatedly denied the allegations against him and said both situations were consensual. In the lawsuit, his lawyers called the allegations a “political hit job — a deliberate and calculated effort to permanently harm Fairfax’s political and professional career and to attempt to prevent him from becoming Governor of Virginia.”

The lawsuit focuses in part on interviews Tyson and Watson did with Gayle King of “CBS This Morning” that were aired in April. The lawsuit said an eyewitness was present “during the consensual encounter between Watson and Fairfax” and accuses CBS of not asking Watson if she encountered anyone while entering or leaving the room.

The lawsuit accuses CBS of intentionally failing to investigate leads, some of which were provided by Fairfax’s team, and of not asking questions that Fairfax’s spokeswoman suggested it ask.

The lawsuit said “a current CBS legal officer, who was a Duke classmate of Watson’s and Fairfax’s, had information all along that Fairfax did not rape or sexually assault Watson.”
