Good attorneys are trained to interview and cross-examine witnesses in a logical way. One important tenet is not to ask a question in court to which they do not know the answer.

Of course, as Congress doesn’t have the information, it can’t ask questions that advance an inquiry in a court of law.

The Mueller testimony before Congress also is a different type of inquiry. What’s more, Congress hasn’t heard from Mueller directly, nor has Barr and the DoJ provided the unredacted report and its accompanying evidence and documentary materials to Congress as required by law.

That lawlessness also shows why this appearance by Mueller is so important: We the People finally have the opportunity to hear for ourselves the answers to important questions.
