As we all know by now, Governor Strickland's Public Safety Director, Cathy Collins-Taylor, is one of the central figures in the scandal.
Based on e-mails and phone calls as broken down in this very well reported investigation by WBNS, Collins-Taylor is in the position to detail specific discussions made over the phone between herself and Strickland's Chief Counsel, Kent Markus.
Additionally, thanks to some particularly inept governing by Strickland's Administration, he failed to get Collins-Taylor approved by the State Senate.
This puts Collins-Taylor in a precarious position. If she wants to keep her job and be approved by the Senate, she will have to satisfactorily answer all questions under oath about Troopergate. If she fails to do so, the Senate will have every reason to not approve her appointment.
This should be fun to watch.
In the meantime, if you're trying to get up-to-date with what this scandal is all about, I highly recommend you read this story by WBNS, and also note their links at the bottom of the page to other stories on Troopergate.
By the end of it you'll be left wondering if we may end up seeing Kent Markus himself working at the Residence if he behaves well in the state penitentiary.
