There is no cover up. If there was a cover up, Trump would have ended the investigation a year ago or more. If there was a cover up, Trump would have exercised executive privileged, but instead turned over all of the information requested by the Mueller team.
He is now declassifying what the Dems don't want declassified, what they prefer to remain covered up, documents on the Russia investigation.
And no you do not have a right to see it in full. It would be a violation of federal law for you to see it in full. You have access to what you are legally entitled to.
As for Mueller, whether he testifies or not, I don't really care. That is something for him to hash out with the judiciary committee. If he testifies you will see it. But is not under any legal obligation to testify.
