He's described on the WABC website as a "guest host". Sounds like Citadel isn't paying him under his old contract and has simply hired him for some shift work on their New York station. Since KABC is no longer using him in a similar capacity, a fill-in shift on KFI doesn't compete with any work he's doing in this market. I suppose that if he manages to get Red-Eye Radio going again and KABC picks it up, that would put the kibosh on future KFI fill-in gigs.
