as much? >> we made the phone not so that you would use it all the time. we made the phone to make your life better. my simple rule is, if i'm looking at the device more than someone's eyes, i'm doing the wrong thing. >> reporter: apple's rollouts come at a critical time for the company. sales of the iphone continue to sag. and the ongoing trade war between the u.s. and china threatens its core business. how hard is apple getting hit by trump's trade war with china? >> currently, the chinese have not targeted apple. at all. >> reporter: if there's a 25% tariff on the iphone xs alone, it could add $160 to what is already a very expensive device. would that hurt sales? >> sure it would. i'm hoping that doesn't happen.

the iphone is made everywhere. it's made everywhere. so, a tariff on the iphone would hurt all of the countries. but the one that would be hurt the most, is this one. >> reporter: president trump calls you a friend. how would you describe your relationship? >> we've had straightforward discussions, many of them. he listens to the comments, which i appreciate. sometimes he doesn't agree. my philosophy on things is you always engage. even when you know you're going to wind up on opposite sides. >> reporter: there's many other ceos and tech leaders that won't meet with president trump. but you engage with the white house regularly. >> i do. and i'm proud to. i don't believe in the i disagree with you so i don't want anything to do with you. the way you stop the

polarization is to talk. this is sort of like step one. i don't want to be a part of the problem. i want to be part of the solution. >> that was wide ranging, interesting. and tim cook doesn't sit down for those interviews often. i hear he had a warning for you about the 2020 election? >> reporter: that's right, david. when we asked him if he's worried about fake news ahead of the presidential election, he responded that he is worried. that fake news is not under control. he says that outside forces are using it to manipulate the way we think. and without using facebook by name, he suggested that platforms like facebook amplify fake news with the news feed and that it can't be solved with artificial intelligence. >> interesting. nora, thank you very much. you can see more of the exchange about fake news and nora's interview with tim cook. we have an extended version on our website, cbs news.com.

diets that are lowering. >> i feel like cardologists have said, limit how much red meat you eat? >> red meata lot the red meat i fatty with saturated fats. a lot of it is full of sodium. this study looked at lean red meat and unprocessed red meat. in addition, what's interesting is that recent research has shown that when you eat a lot of red meat, you change your gut bacteria. you produce a chemical that can be plaque-producing. >> more plant base, less meat. coming up next, why the world health organization is investigating the deaths of an american couple vacationing in the south pacific. and the mass shooting in virginia has prompted the governor there to make an unusual move.
