KARL: I understand that neither of these two senators we're talking about now have been allies, to say the least, of the president. But this has been an extraordinary series of attacks on the president, from major figures in the Republican Party — not typical political attacks. I mean, saying the president is responsible for the debasement of the nation, that a breakdown of civility is the fault of the president and that enough is enough. We've seen similar remarks from John McCain, the party's former nominee. In any of this — does any of this make the president pause and wonder if he is doing anything wrong, if he bears any responsibility for what these senators are saying is a breakdown of civility in our country.

SANDERS: Look, I think the voters' of these individual senators' states are speaking in pretty loud volumes. I think that they were not likely to be reelected, and I think that shows that the support is more behind this president than it is behind those two individuals.
