The Obama White House is attempting to regrow the wall between political and constituent concerns and law enforcement concerns.
The Department of Justice should operate with the most minimal of political interferences (since I don't think it's possible to avoid them all together) with the goal of maintaining its independence.
That said, I absolutely do think that what Chris Dodd has been doing is not above board. I don't know who has jurisdiction or who to inquire with further, but the White House isn't the right place. I'd be interested if someone knows who in the DoJ would be the appropriate folks to contact.
