The special counsel investigated the accusations, and found the accusations to be lacking.
The Senate approved Attorney General made the final determination. You're aware the AG needs to be confirmed by the people's elected representatives in the Senate, correct?
The President has been vindicated and cleared of any wrongdoing, the Democrats in the house have no right to see the personal and private information of an innocent man. The Supreme Court with Brett Kavanaugh would have no choice but to strike down the Democrats attempt at gaining the full and unredact report in the name of preserving an individual's right to privacy, and so overzealous prosecutors can't publicly humiliate people that they failed to convict.
The Democrats will either accept the redacted report like adults, or be made to look like sore losers crying over sour grapes all over again. I assure you, the latter isn't a good look going into 2020.
