bernstein. you've written extensively about michael flynn.signation being forced out this week. >> well, my actions is the media did -- they were able to get information that was pretty stunning given how quickly the information did come out. i think that represents one kind of leak which is the kind that happens when people inside the government, good people who want to do right thing by the president, by the way, are very, very worried about what's going on inside. that's where you get people leaking transcripts or the summaries of transcripts with foreign leaders. you saw that with australia. you saw that when flynn talked to the russians. i'm not surprised. i think the flynn matter is a culmination of things. it's not just this one thing as we reported before and others did. flynn is rather erratic person and i can't imagine that they wouldn't have discovered that sooner rather than later. >> you're describing the motivations of leakers. carl, i wonder if you can provide some insight into this as well. you've been working anonymous source
