re: What was Muller investigating?

The problem with the Special Counsel provision is that it allows the Special Counsel to operate with very little checks and balances and allows him/her to go on special tangents that would otherwise not be investigated and has no relation to the original matter like .....Ken Starr and Fitzgerald.

When it was basically proven that Whitewater was a land deal that went bad but was otherwise arms length wit no shennanigans, Kenneth Starr should have wrapped things up and said, " That's it, I'm going to Baylor to help facilitate rapists on the football team." Instead he takes a referral in a civil case in a state court and blows it up. Fitzgerald decided on his own to expand the scope of the investigation to get Scooter Libby who other than misremembering some dates did nothing wrong. Richard Armitage leaked to the press and got off with nary a slap on the wrist

The SC almost operates as a 4th branch of the government...last I checked, the Constitution only provides for three
