For what it's worth... [Nixon's \(first?\) Attorney General](https://en.wikipedia.org/wiki/John_N._Mitchell) was corrupt and played a role in orchestrating Watergate.  [His last attorney general](https://en.wikipedia.org/wiki/Elliot_Richardson#Cabinet_career) refused to go along with Nixon's bullshit.  

If nothing else, this should show that having a corrupt AG on your side won't necessarily help you and/or not everyone is willing to stick their neck out to save the asshole-in-chief.
