what a person tweets around does not affect his ability to lead this country or his or her ability to be an effective ceo. >> the tweet is a form of communication. i they think the president is crazy. >> that's a terrible trivialization. i thought that julia made a really good point. >> we're going into 360 or something. >> how do you know when we have a serious thing happen in this country? how do we know? how do we trust it? >> can we continue this conversation in the next block? don't go. we'll continue. we'll be right back.
