It is a criminal investigation. Several possible crimes have been identified. Lying on your SF-86 is a crime. Most people would have at least lost their security clearance for things like omitting over 100 foreign contacts. Several campaign officials illegally accepted money from foreign governments and then tried to cover it up (Flynn, Manafort).
None of this implicates Donald Trump himself, and I wish he would stop fanning the flames. But as I said, I’m not going to second-guess his political instincts. I would not be surprise if all this hand wringing about “what is Trump doing?!” turns into jubilation of “I see what he was doing! Nicely played!”
But we’ll see.
You are making big assumptions that they were intentionally lying (which didn’t come out until after Sessions recused himself) and that the money was illegally accepted or had anything to do with the campaign or election. Noone has stated that those are “crimes” — what is happening is an “investigation” in search of a crime. You along with the Left have predetermined that a crime was committed. Again, to my original position, the law did not require Sessions to recuse himself. We’ll just have to agree to disagree.
