JOHN BRENNAN: I think we all should be very worried about what the president might do in order to try to interfere somehow in the integrity of the upcoming midterm elections.
He has tremendous authority in terms of the president of the United States. And if he believes that either house is going to shift to Democratic control, I wouldn't be surprised at all if he's going to pull out all stops and use, as he says, every tool at their availability.
And with a Department of Justice, as well as with a Republican Congress willing to support him, again, I think we have very legitimate reasons to be very concerned and worried.
