Nothing requires the process to be fair or accurate. A good deal of what the government does is garbage - at best.
It can get worse. See the prosecutor elected in San Francisco. Imagine a House majority of AOC. The Senate is a beyond-repair corruptocrat club. Rome didn't fall in a day.
How was that official?
That vote was just a “keep doing what you’re doing, with rules” resolution - didn’t seem the proper start of an official investigation.
