The Democrats don't have the power to "require" all the Kavanaugh papers.
As I said in my previous post to you, I believe it is up to the majority chairman Senator Grassley to determine when the committee votes and I know that it only requires 51 votes on the floor to end debate.
Grassley isn’t going to arbitrarily change the way the Senate committee process works.
Republicans got to see the papers of Kagan and Sotomayor in their confirmations.
Democrats will be allowed to see the papers of Kavanaugh.
