To start with, if I were president for a day or advising the president (which I did 12-14 years ago), I’d summon the AG and the FBI Director to the White House and direct them to advise me of the primary targets of all ongoing CT investigations - all file classifications (there are eight categories) - in the Hamtramck (Detroit Field Office) and see how many of their “city leaders” are implicated and how. We’d play it by ear from there...
I'm not sure I like the idea of using the FBI and the Justice Department to investigate politicians without cause.
