apply to violations of the law. so, giuliani's heavily exposed here. he knows it. the whistle-blower may be exposed, but he or she did the right thing. we need to look at others who are not doing the right thing, call them to testify, get them to tell us what they know. >> here's an interesting angle, though, put out by the "washington post" in a new article, which writes that the president and the public disclosures have become routine and "on the implicit theory that the president's alleged offenses can't be that serious if he commits them in full public view." why does this matter? why is it a danger to national security? >> well, first of all, the president doesn't get half of the national security implications of what he does, and i think this is exhibit "a." he thinks this is totally appropriate. he's said repeatedly, it was a beautiful conversation, totally appropriate. i'm telling you that right now the president of ukraine owns this president. he could come out and tell us exactly whether this president did something inappropriate or not. we don't want our president in that shape.
