The World Publishing Company (i.e. the Tulsa World) is suing conservative blogger and Urban Tulsa columnist Michael Bates for libel. Also named in the case is Keith Skrzypczak, the owner of the Urban Tulsa Weekly, and the Urban Tulsa's publishing company (Renegade Publishing Inc.).
You can read Michael Bates' take on the suit here. The Tulsa World has an article here. They contacted Bates 45 minutes after the lawsuit was filed, asking for his reaction (like he would know about it yet?).
