Sundance lays it out nicely, but I question his conclusion that Rosenstein is a White Hat
I’d love to believe Rosenstein is a white hat, but for it to so, Mueller would have to be one of the good guys as well. Just not buying it.
Recall that Rosenstein essentially attempted to have Trump appoint his own pseudo-Special Council by recommending, and escorting Mueller for his interview for FBI Director. Failing that, Rosenstein the very next day appoints Mueller as SC. Logic dictates that Rosenstein was determined to have Mueller investigate Trump.
