The Scott Roeder and Operation Rescue Connection
Rachel Maddow does a disturbing story about the connection between George Tiller's accused murderer Scott Roeder and Cheryl Sullenger of Operation Rescue. Sullenger originally denied knowing Roeder. Evidence later forced Sullenger to admit she had several telephone calls with Roeder. Sullenger used her Twitter account to track Dr. Tiller.
An interesting sidenote is Sullenger went to prison for attempting to blow up an abortion clinic.
