after president trump became president. let's talk to cnn military and diplomatic retired rear admiral john kirby. jeff zeleny, let me start with you. rudy giuliani, one of the things he said this morning was these three prisoners were going to be released today. does he know something we don't know? what are i hearing from your sources there about the timing of this? >> reporter: dana, that is the great question here. there is a sense they do believe, u.s. officials do believe there will be a release. the ones we have been speaking to all morning long say they're not sure exactly when that will be. but i can tell you, you know, the whole reason this is happening, of course, is because of those broader discussions under way between a summit with the u.s. president and the north korean leader. but there is frustration here at the white house about why rudy giuliani, the president's outside lawyer who does not have a security clearance, is the one talking about this. you get the sense that he wanted to change the subject.
