Comey’s leaks had a great deal to do with the appointment of a Special Counsel. This was a setup even before Trump took office. Comey was writing up notes after every meeting.

Wiki says Rosenstein is a Republican. He has been appointed to various government positions by both Dim and Republican presidents. He is a long term swamp creature who has worked for multiple administrations.
I agree he's been a disastrous appointment, but he is not a hard core Dim. He mostly seems like a guy who panicked and appointed a special counsel mostly to take the heat off himself.
