Check out footnote #17 on page 5 of the criminal referral letter. Since Rod Rosenstein may be implicated for spying on Carter Page, anyone investigating FISA abuse should not report to Rosenstein.

"Accordingly, neither US Attorney John Huber nor a special counsel (if appointed) should report to Rosenstein." Sounds like Huber is already 'going there' doesn't it?
