Mr. President , as we look to the future, i am confident that our common values and shared interests will continue to unite us. Reporter President Trump returned the favor. On behalf of all americans, i offer a toast to the eternal friendship of our people. Reporter the official royal welcome came earlier in the day out in the palace garden. The attire, undeniably british. The music, unmistakably american. u. S. National anthem playing the royals are masters of pomp, but the circumstances this time around are a bit unique. President trump insulted his royal host just days before he arrived, calling out prince harrys wife, the american meghan markle, for her criticism of him during the 2016 election. She said shed move to canada if you got elected. Turned out she moved to britain. Well, that would be good. There are a lot of people moving here. So what i can say . No, i didnt know that she was tsty. Reporter the president then denied he said it, both via tweet and on camera. No, i made no bad comment. Thank you. Reporter in london today, the president did what president s do, including laying a wreath at the tomb of the unknown warrior. But again, its what he said thats creating diplomatic drama. On the eve of his visit, the president criticized outgoing Prime Minister theresa may for her handling of brexit negotiations. He waded into british politics, all but endorsing Boris Johnson as the next Prime Minister in the middle of a highly contested election. And, just minutes before touching down in london today, he called the citys mayor, sadiq khan, a stone cold loser via tweet. The two have clashed in the past, and khan says President Trump does not deserve a state visit, preferring instead that the royal family roll up its red carpet. Now, some of President Trumps controversial comments may fuel protests that were already planned to take place here tomorrow. Also tomorrow, more of the ceremonial events are over, and President Trump gets down to business, in a meeting with Prime Minister may. David . Begnaud thank you, ben.

Norah odonnell, the incoming anchor of the cbs evening news, actually spoke with apple c. E. O. Tim cook. Reporter when i listened to that today, that new innovation thathat apple signon, i shot at the way facebook and google is using all of our data. You know, were not really taking a shot at anybody.

Were moving privacy protections forward, and i actually think its a very reasonable request for people to make. Reporter do you think facebook cares about our private security . I think that everybody is beginning to care more. People are becoming more aware of what has been happening. Many people are getting more offended. I think this is good, because we need to shine a light on it. You can imagine an environment where everyone begins to think theres no privacy, and if there is no privacy, your freedom of expression just plummets, because now youre going to be thinking about that everybody is going to know every single thing that youre doing. This is not good for our country, not good for democracy. Begnaud norah joins us now from california. Norah, the news was breaking in washington that the federal government is looking into big tech, including apple, as you were doing the interview. Did you have a chance to talk to tim cook about this . Reporter we did. And let me tell you about that in just a minute, because that key point there, privacy. The c. E. O. Of apple, tim cook, believes that privacy is a fundamental right. And thats why here at this Worldwide Developers conference, he not only talked about new privacy tools, he talked about new software changes, some new hardware with the new macbook pro. All of that addressing what he believes are concerns of users. On that question about whether apple is too big, the c. E. O. Said, i dont think anybody can reasonably conclude that apple is a monopoly, and he said, i think that the scrutiny is fair. I think we should be scrutinized. So, much more to come on that. David . Begnaud norah odonnell, thank you very much. More of norahs interview with tim cook actually airs tomorrow on cbs this morning. Her full report airs tomorrow on the cbs evening news.
