Rahm's Connection to IRS Scandal? Chicago Media Shy About Asking Questions of Former Activist Chief of Staff

The Chicago Sun-Times and Chicago Tribune seem to be quite shy. Why hasn't Rahm Emanuel been questioned about what he knows about the IRS scandals. Did they start when he was Chief of Staff? After all, this wouldn't be the first scandal Rahm has been involved in. If Rahm helped cook the books at Freddie Mac: should we expect the worst on he knowledge and/or participation in the IRS scandal???
