Lindell cannot have any proof that dominion did anything wrong, but I'm a little suspicious about "how much" dominion can get from an individual. Now Faux and Newsmax ...... if they "publish" Lindell's false statements without lableing them "opinion" or if they made any new report asserting dominion in fact did something wrong .... then I think they have a problem.
But Lindell will have to pay to mount a defense, which may be dominion's real intent. He may have a defense, or not. He may have been told he was spouting a lie. If he was, then dominion's only problem is proving what damage he caused.
