Take your pick.  It was either incompetence or bias that lead to the investigation against President Trump.  Either way, it is a sham and it should have never gotten past first base, if that far.

Those guys ruined several lives and they don’t seem to care.  I sort of get the feeling they are proud of themselves.  Right now, I doubt that there are many FBI agents that are proud of them.  Which reminds me.  They also did a pretty good job of sullying the reputation of the FBI for a few decades.
