Bear in mind that the claims were reiterated by Hannity, Carlson, Ingraham et al. Is Fox not responsible for what their own people are saying in their programs?
Can you give me an example of where Carson said something libelous about Dominion?
My recollection is that the best they could find was some email communications from the interviewers saying they didn't believe Sidney Powell, or some such.
So if you are going to allege that some of Fox's staff said libelous things, perhaps you can provide an example?
