It's highly unusual for a suit like this to be settled such a short time after the suit was filed (less than two months). I suspect Carlson had audio and video files to back up her claims, and the pigs who run FOX were scared sheetless that she'd release them on the internet.

Of course the primary target of the suit, Roger Ailes, is now an advisor to the Trump campaign. Sadly, that makes perfect sense ...
