wynton: great, i love duke. duke's intelligence, dedication, over 2000 pieces, i love him. because i grew up listening to classical music, i love beethoven. david: what about dizzy gillespie? was he an influence on you? wynton: the thing about him that hit me first was the depth of his intelligence. i met him when i was 14. just when he started talking with my dad and other musicians. dizzy was very intelligent. he's part of the reason we developed jazz at lincoln center. i did not want to play in a big band. i always wanted to play small band music. dizzy told me -- i called and asked him what he thought i should do. he said to lose one's orchestral heritage should not be considered an achievement. so he was telling me you need to figure out how to keep our orchestral heritage, we paid a lot of dues to build up orchestral music in jazz. for us to give it away and say big band is old-fashioned, that's not intelligent. david: let's talk about jazz at lincoln center. you began playing jazz at lincoln center in the late 1980's? wynton: 1987. david: that evolved to jazz at linc

it out legally juking out duking it out in front of the judge their supporters again we've already seen them taking to the streets the election night has already seeing scuffles and violence as protesters clash between each other not anything significant but again this could be just a very very small ignition which could grow into a full on wildfire all across the united states this is certainly the concern that is being reiterated and echoing all across the social media and so on and so forth for instance just to show you a little bit move these protests and these demonstrations coming from both sides here they are right. now it's easy to understand where the discontent is coming from because people on both sides expected to waves they expected tsunamis just a different color as people in joe biden's camp expected a blue wave and in trump's count. explained they expected a red tsunami. neither of that happened and the elections are really really close they're heavily contested so people are already growing tired they are already tired of not knowing who's going to be in the oval office

since the era of the duke of wellington the mod's not very good of managing big expensive projects. what are you going to do about that? but first, the prime minister had been hoping to use the week to reset his relationship with the public and his party, after the departure of his controverisal adviser, dominic cummings. but his plan was dealt somthing of a blow when borisjohnson was forced to self—isolate. the prime minister used a video to announce that he'd been "pinged," as he put it, after a meeting with an mp who later tested positive for coronavirus. borisjohnson doesn't have the illness, but is staying in his downing street flat for another few days in line with covid rules. at prime minister's questions, at which he appeared by video link, the labour leader wished him well, but questioned how easy it was for other people to follow the self—isolation regulations. the prime minister is doing the right thing by self—isolating after being notified by track and trace. but does he think he would've been able to do so if, like so many other people across the country, all he

we have to look how we influence the demagogues that came after him whether it be duke, george wallace or people who are in the political context today. i want to say one other thing. the temptation with a lot of the interviews i've been doing on mccarthy's to talk about donald trump, and this is really a book about mccarthy. donald trump's name is mentioned in the preface and the epilogue and yet his story and the story of others is there in a way and every page of the book. >> and as long as you brought trump up i'm going to join you and try to avoid a deep discussion of him, but tell me when you started putting this book together it was around the start of his presidency, wasn't it? >> a week before the election i signed up to write a different book and that was the biography of barack obama and the day after the election i realized we wouldn't know the legacy until after the era of trump is over and it became apparent to me the day after the election what i thought was a story of also ancient history in terms of demagoguery was a story today we have not outgrown this affair, this a

how unusual is it to get this sort of statement from the duke of cambridge?m it to get this sort of statement from the duke of cambridge? in a word, very, very unusual. i can't think of another time that a senior member of the royal family has offered commentary or criticism, or whatever you want to call it, about media coverage. it'sjust not whatever you want to call it, about media coverage. it's just not what they do. instead, i think quite words i had with senior executives. instead we have had this very public statement addressing a very hot and controversial issue. so it is surprising, it is rare, i think it is pretty much unprecedented. it is also worded in a very careful way. you highlighted that his office described this as a tentative welcome. he himself, the prince, described it as a step in the right direction. this isn't a kind of slap on the back and a well done boys. this is, i've got my eye on you, i'm interested in this, i'm keeping watch over what happens here. so it is very interesting, it is pretty much unprecedented and it is very heavily

when i went to duke university we were on two television games. the whole season i'm talking about basketball. they were very good teams but nobody knew who mike was except me he was on television twice but now they know everybody so it just changes the whole dynamic for sports. that is a major change in my opinion. the money became significantly higher with the Ãbrevenue. a mention was made of the rhodes scholarship. to understand the athletic various accidents have been dropped from qualifications for the scholarship? does anyone know? >> i write recommendations and is still part of it it is still part of it but so students it still part of it but there is not the same i would say expectation but the same focus on being a varsity athlete. and the question in the application essentially relate it to athletics or some sort of physical condition, a lot of students are not varsity athlete but they describe a way in which they exercise the body. it's much more open-ended type of question. >> i would put in a little plug for the book here we have bee

duke and georgia both scratched games against gardner webb this week after that team reported a positive case. and the women's powerhouse uconn postponed its first four games and suspended all team activities because of covid. one thing to keep in mind, though, there are 32 ncaa conferences and they operate across 50 states, which all have different covid restrictions and safety protocols, so getting the teams on the court, it's complicated. cnbc's eric chemi is with us how do all these conferences move forward, eric >> reporter: that's the thing, it's not the ncaa who controls all of college basketball, each conference gets to set its own rules. the ivy league, for example, simply cancelled basketball completely this year, but that's because sports -- it's not a huge revenue generator for that conference but when you think duke, kentucky, syracuse, ucla, kansas, those schools, they rely on basketball television money it subsidizes so many other activities on campus and helps bring in more money in the form of alumni donations, corporate sponsorships and better college rankings from incr
