What are you talking about? Flake voted YEA on Kavanaugh so Kavanaugh moves to be voted on by the Senate. Flake just SUGGESTED an FBI investigation which he has no authority to start.
It's up to President Trump, Mitch McConnell, and Chuck Schumer if there is to be an FBI investigation.
Now once (or IF) there's an FBI investigation #1 it's just a delay tactic we all know it #2 the Democrats will say "but the FBI doesn't make conclusions" once it's done.
And to think the Democrats have Joe Biden (The Biden Rule & "FBI doesn't make conclusions") and Harry "Nuclear Option" Reid and Anthony Weiner to thank for all this....it makes me very happy I wish Andrew Breitbart were alive to revel in this moment which he helped bring about.
