BRZEZINSKI: "I meant the overall investigation. Why does it exist?"
MCCASKILL: "The overall investigation exists because there was a legitimate question as to whether or not Hillary Clinton had done something against the law as it related to classified e-mails. And I believe that investigation was very thorough. Now, they have a few more e-mails to look at. By the way, they have almost 14,000 FBI agents and a budget of $8.5 billion. Seems they could get busy and look at these and tell us by the end of the week."
