Remember the Clinton investigation of 1998 or so. It took a long time to get Bill on. Finally lying about a BJ was found and he was impeached. It was never the original investigative goal. This investigation will find ANYTHING they need to screw Trump. It pisses me off so much, but that is who they are done.
As I recall, Starr was actually tasked with additional areas to investigate.
Mueller seems to be broadening his investigation on his own.
That in itself is troubling.
They shouldn’t be able to just run amuck.
