What do Democrats think Mueller will testify about that he didn't put in his report? Yea.. Nothing. Telling everything he found in his investigation was the reason FOR the report. Dems just like to be on TV. Zero policy ideas.
This witch hunt and continued - and what will be a continuing, harassment of the President is sort of like the Dems saying, "We know Trump is an alcoholic( he says he doesn't drink - ya right!). All we have to do is find where he is stashing his empties."
