Question.

If the Dems take Congress can they investigate the allegations against Kav?

I mean if they can get a rock solid case that he committed perjury or lied to the FBI.
This is still a federal crime right?

So, if the perjury happens in the Senate can the Lower House prosecute or hand it off to a special council? Are there options?

I know impeachment is a waste of time but even that delegitimatizes anything he touches.
