Blumenthal: Devin Nunes Has to Step Down

EXCERPT:

BLUMENTHAL: "He has to step down, even if it were only the appearance of what he has done. There is a reality of potential impropriety as well. He would have to step down to ensure the objectivity and impartiality of the intelligence committee investigation. For him to suggest that there’s no question here, 'Why should I,' is really an insult to the American people and to the institution of Congress."
