I’m not aware of one. He often does a few moments on Jake Tapper’s show and has a website, SteynOnline, where he writes articles and sells some Steyn-related swag. He sings (with others) and sells CDs.
Mostly I know him from Rush’s show and hope he gets a syndication gig.
He tried it once and it ended disastrously. Mark came out of it whole, but I’m sure he’s very wary of doing anything like that again. You can read all about it on his website. It’s a long story.
Tucker Carlson is who I meant. Not Jake Tapper.
