Transcript for Leaders react to North Korea's cancellation threat
That is a certainty. Thank you, Martha. Cecilia Vega here as well and let's stay on the theme. The president had pretty high expectations for this summit. Any initial white house reaction? They released a statement saying they'll continue to coordinate with allies, that they're looking into the reports from the south Korean media and the summit from the white house's perspective is still being planned. This caught the administration off guard. There is this now push to find out as robin said whether this is a negotiating py by Kim Jong-un or whether this is actually something they need to take seriously. For now it's still going to happen. This is a setback, unclear exactly how big it is. What the president said when he talks about it always talks about, yes, they're agreeing to denuclearize. It's clear that both have different definitions. Completely but remember the president has also carried through everything he said -- left this window open that things could fall apart on this. He has always said, I want to sit down with him but it may or it may not happen. So as Martha just said, is there anyone more unpredictable than Kim Jong-un? Hard to know right now. One more thing. This white house focus on leaks is really getting intense. Yeah, they cannot get this one under control. There is a push afoot, perhaps for some people to lose their jobs over this latest leak about the comments these grotesque comments about John McCain that happened in the staff meeting. There are reports out there that there are sweeps happening in the west wing right now looking for personnel -- personal phones inside the west wing that have been banned and the president is calling these leakers traitors but we've got to remember these are people he hire they are on his team. People leaking about his own administration. Inside his white house, Cecilia, thanks very much.
