I am concerned that they wanted the FBI investigation for other reasons.
Sen Leahy wanted Bush documents from when Kav worked there. It has to do with a Republican Aid who had access to a shared server with dems and repubs who leaked a draft letter from Leahy regarding their plan to interview judicial candidates.
He was asked if he knew (in Sep) the letter was stolen. A Repblican Senate staffer sent an email to Kavanaugh during the period when Miranda was taking information from Democratic senators. This email had the subject line spying and it informed Kavanaugh that we have a mole within the Democrats ranks that was providing Republicans with information.
Kav said no. Leahy thinks he committed perjury. This FBI investigation might lead to getting those confidential documents that Grassley refuses to release.
1) The Rats want to destroy,or at least neutralize DJT.
2) The Rats know that Kavanaugh is another Thomas/Scalia
3) The Rats think that Kavanaugh will vote to strike down Roe v Wade
4) The Rats are looking at this November and 2020 and think this will help them both ways.
This list is not necessarily in order of importance
"Leaky" Leahy thought that Rapin Bill Clinton didn't commit perjury, when he did.
Does Leaky want to go "clubbing"?
