Senator Jeff Flake cut a deal with the Democrats to vote against Kavanaugh unless the FBI is allowed a one week investigation, supposedly to cover only those items an accusations on record with the Senate at this time.
That seems fair, although it does justify DiFi's scheme to keep Dr Fords letter secret untill the final moment. I doubt the other Dems will go for just one week, because that goes against the purpose of delaying tactics in the first place.
We will see.
