Transcript for Deputy attorney general made decision that a special counsel is needed
As Jon reported right here on this broadcast, the white house was given just 30 minutes' notes before the justice department revealed a special counsel. The deputy attorney general who decided the special counsel was in fact needed, rod Rosenstein was on capitol hill today, making his case as to why. The president as you heard calling this the biggest witch hunt in American history. But a key Republican, tonight, with advice on the president on how he should be handling this.
