Morrison is (unfortunately) the Atty General of Kansas now. He used to serve under Phill Kline but switch parties to Democrat so he could run against Kline. Kline was investigating Tiller and Paulie didn’t want that.
Sebelius doesn’t want Tiller shut down either. She’s raked in tens of thousands in donations from Tiller, and even appointed one of his lawyers to the Kansas Sentencing Commission.
Morrison was Johnson County DA. He didn't 'serve under Kline' any more than Kline, having accepted the JoCo DA position he vacated, serves under Morrison.
