Do You Really Need Attorney General Merrick Garland to Answer Questions From the House?

David Rothkopf: Merrick Garland should be subject to questioning by Congress. He says if the House asks him about specific cases, he has to tell them respectfully to go to the House. If AG were to capitulate and answer questions on pending investigations of Donald Trump or Joe Biden, it would jeopardize those investigations potentially fatally, writes Rothkopff. The Justice Department must categorically reject any such incursions by the legislative branch, he adds.
