I hope the turtle says nothing until Monday morning and CALLS THE VOTE!
The interesting thing about this is that the FBI's avenue for investigation is very limited. Judge likely will refuse to speak to them, and they can't make him. The other witnesses identified by Ford as the only other people present have sword they don't remember anything. So all they can really do is interview Kavanaugh again -- which is pointless given his flat denial. Or Ford, and try to ask her about more of the odd details in her story.
Not sure where that gets anyone other than a delay, which is obviously part of the point. But Flake himself said it is limited to one week, so even that isn't much.
