Sitdown with twitter cofounder jack dorsey. The media platform is used by 300 million people, including the president of the United States. Im sure you hear from the same people i see on twitter who are maybe progressives or democrats who dont like donald trump and they say how can you give this man a platform to say all of the things hes been saying since he started to run for president. How do you respond to them . I believe its really important to adhere to our leadership and its really important to hold them accountable. Our sunday sitdown with twitter cofounder jack dorsey. Lets begin with the latest Ballistic Missile test by north korea, a country President Trump has put front and center on his Foreign Policy radar. Nbcs Janis Mackey Frayer is live in beijing with the latest. Janis, good morning. Reporter good morning, willie. The test, by all accounts, success. Traveling 440 miles before dropping into the sea of japan near russia. It was launched from the northwestern city of kusong, a site of the launch in february. Japans government taking note of the altitude, saying it reached 1250 miles leaving experts to believe it may not be the intercontinental Ballistic Missile that the north has been threatening to test but is likely capable of still reaching u. S. Military targets in the pacific, including guam. The timing of the test is a challenge to south koreas new president who was sworn in just last week. He said today it was deeply regrettable because hes open to talks with the north if the conditions are right. Thats president President Trump had echoed and just a couple of days ago had a top north korean enjoy to the United States said that the regime would be open to that, too. It seems counterintuitive but if you look at the track record for north korea and its knowing that talks are in the cards. But this is an embarrassment for china. This is the opening day of a huge summit being hosted by xi jinping. 29 heads of state are here, including russias vladimir putin. Some call this chinas Marshall Plan and the centerpiece of global strategy. This is bound to test the patience of beijing during unprecedented frustration with north korea. Willie . In china, a country that is supposed to be able to rein in north korea. Janis mackey frayer, thank you. There is a fallout from the firing of fbi director james comey. Kelly odonnell is live for us at the white house on this sunday morning. Kelly, good morning. Reporter good morning, willie. Picking up on that first the white house was briefed on the trajectory of the north korean test saying in a further written statement from the press secretary, north korea has been a flagrant menace for far too long. Let this latest provocation serve as a call for stronger sanctions against north korea. The president has no Public Events on this mothers day but sources tell me hes working towards a very big decision, his choice for fbi director. The search is on for a new fbi director. How did it go . Reporter a string of contenders visited the department of justice on saturday arriving on foot and behind darkened windows. President trump says he will make a decision soon. Possibly this week. Very well known, highly respected, really talented people and thats what we want for the fbi. Reporter eight backgrounds completed round one of interviews while the former director fired by President Trump, james comey, was briefly spotted at home on saturday. He has not spoken publicly. After the president s provocative tweet suggesting tapes may exist of his conversations with comey. President trump did not respond when i asked if tapes exist. Mr. President , are you recording any of your meetings with the white house . Are you recordings any of your meetings . Reporter in an interview on fox news saturday night, the president says hes surprised by the comey firing fallout. Look, i thought that this would be a very popular thing that i did. All of the democrats couldnt stand him. But because i terminated him, they say, ah, we get political points to go against trump. Reporter frustrated by media coverage, he called press wonderful human being. Hes doing a good job but he gets beat up. Reporter will he be there tomorrow . Hes been there since the beginning. Reporter the president delivering the commencement address at liberty university. In my short time in washington, ive seen firsthand how the system is broken. Reporter and gave students advice with a familiar ring. Being an outsider is fine. Embrace the label. Because its the outsiders who change the world and the real and lasting difference. Reporter and the timeline for making a decision about the fbi director is affected in part because of the week ahead the president has. He will be making his First International trip leaving at the end of this week visiting saudi arabia, israel, italy and belgian. Advisers say he needs space to prepare for that trip. Willie . Kelly chuck todd is moderator of meet the press. Good to see you. Good morning. This was supposed to be the week of sally yates. Her testimony was on monday. It seems like a lifetime ago. A day later, President Trump fires his fbi director and what followed from there was the mixed explanations of what happened and why it happened. Now he wants to nominate a new director. What ind could of a choice do you expect him to make . Reporter well, if you look at the list of folks, he could go down two different paddles. One is an official path, which i think in this environment is a little chanshaky. You have senator cornyn, and with charges of politicizing this investigation, i dont know of somebody who sort of made their career in Public Service with a Political Party i. D. Is going to be able to get through. I think the is the most intriguing. Shes a former clinton official, former bush official. Been on television as a security analyst. We know the president likes to have people that can handle the media spotlight. I think of the folks on that list, shes the one that strikes me as the one that can get the broadest bipartisan support. Do you think hes going to go for a loyalist, chuck . All of this reporting is that he asked james comey to pledge his loyalty, a charge the president denies. Can he afford to do that at this point . Look, on paper, no. It seems like, of course not. That doesnt mean that he might not do it. Plenty of people told him firing comey last week, you may want to get rid of him, get your ducks in a row, take your time, have somebody lined up. He didnt listen to that either. I dont think he can. I think the safest thing to do is to find somebody that democrats would feel comfortable with but clearly, from the reports were getting even about cabinet with lately, its the ones that dont show more deference to him are the ones that are in trouble. Chuck, im going to talk about what is going on inside the west wing right now. For two days after the firing of jim comey, you had everybody in the white house, including the Vice President of the United States, by the way, saying that President Trump made this decision based on the recommendation of Deputy Attorney general Rod Rosenstein, that he recommended to get rid of comey and then donald trump sits down with lester holt and says he made that decision before he even heard from rosenstein. How do you explain that from the white house, people going up in the Briefing Room and tell one story and then a president who completely contradicts it . It seems what happened here it was a decision in search of a rationale, a decision was made and then a rationale created. And i think the operative side of the white house who comes from more of a professional political operative background were just that rationale. And then, of course, an intervening event happened. It appears that Rod Rosenstein didnt like being used as the rationale and then the president said nope, its on me. I think what you have here, willie, based on my own reporting and watching all of this, you have a president whose inner circle has gotten much smaller and that inner circle has communicated this decision to the traditional inner circle of a west wing who right now isnt quite sure whats in the president s head. Thats a recipe for disaster right now, which is why theyve got to fix this problem inside that west wing. Its something that even the Vice President doesnt know whats going on inside the president s head and contradicts him. Chuck, ive got to thank you. Ive got prime swag right here. I have a meet the press mug you sent from washington. And ive swimming pool. Its giant. Its a twogallon coffee mug. Literally. I have a full cup. Cheers. Happy mothers day to mrs. Geist. Thank you. And to you as well. All right. Ill be sitting with my new mug watching meet the press and Chuck Schumer and Rex Tillerson and Lindsey Graham will be on the show. Cyberattacks were worst than we thought and fears that bigger attacks could be coming. Nbcs Kelly Cobiella is following the story from london. Good morning. Reporter good morning to you. This is being called a worldwide attack on an unprecedented scale. This morning hes saying there are now 200,000 victims in at least 150 countries and warning ou turn on their computers. Britains National Health service computers were the first to be hit on friday forcing Emergency Rooms to be shut down, stopping surgeries, doctors, hospital staff werent able to access patient records or anything else on their computer networks. Britains Prime Minister theresa may says thats returning to normal. This virus has since spread to car manufacturers, russian banks and the countrys interior ministry, transport systems in europe, universities in china and Federal Express in the United States. But listen to this. A 22yearold cybersecurity blogger known as malware tech may have saved the day by accidently finding a kill switch for the virus and slowing it down. He said he was surprised by the virus lack of sophistication. This ransomware affecting a computer an email and quickly spreads throughout a Nations Network encrypting files and demanding 300 in bitcoin to unlock them. It was based on a hole in microsofts security and then leaked by hackers and this morning that blogger who helped slow down the attack is warning users to update their computers fast. He says its only a matter of time, willie, before cyberthieves get around that kill switch. Willie . This is just the kind of attack that they have been dreading for some time.

Were neutralizing. Maybe i want to neutralize. You ever think of that . All right. Dylan and i are already to whip through the highs and lows of the week. The persistence of one young man pursues an apology from the Vice President of the United States. Vice president pence was speaking graciously to military families in washington this week and thanking them for their sacrifice when he threw a gentle backhand right into the grill of a boy standing behind him. After the remarks, the Vice President greeted the children and the boy trailed him all the way looking for thank you all for coming. The boy finally cornered the Vice President who quickly apologized for the accidental smack. No harm, no foul. That kid is persistent. Thats right. He wants his apology. He knows his manners. It didnt look like that big of a hit. It wasnt. Our first low is the feeling when you are the only one left out of the party. It stings especially when youre a black bear who loves brownies. Lets head up to avon, connecticut. The smell wafted out into the woods and the bear made it clear he wanted in on the brownie bash. The bear pealed open the screen door and pushed his paw and nose against the glass to get just a little bit closer to that beautiful smell. When no invite was extend went around the house trying to get in. She called 911 but the bear bailed by the time the police arrived. He wanted to add it to his picnic basket. Half adorable, half terrifying. They look cuter than they actually are. Yes. Our next high goes to a Convenience Store employee with lightning quick fingers c. He performed the normally monday task of taking beverage inventory. Theres another mundane about the way this guy works the cooler. Hes recording the inventory at that speed and its mesmerizing. The clerks speed was calculated at about 80 words a minute. Hes been doing this for 30 years and all of that practice shows. If you want to sleep well minute. It lulls you to sleep. I dont believe hes typing anything in there. They are going to get extra orders of milk. Exactly. And for all of you moms with little ones, center of gravity to one Power Lifting russian baby. He made himself an online superhero when he was recorded pulling himself up on his own crib and rearranging the furniture. Keep in mind, he cannot walk. He can drag a giant crib across the room in a crinkly diaper. He sets the crib down right where he wants it. The boy immediately became the favorite to win gold at the 2020 olympics. Thats incredible. I must break you. Look at that kid. Ever seen calvin do that . No. This is a bonus high. Will ferrell giving the commencement speech where he whitney houston. And i will always love you class of 2017 [cheers and applause ] and i will always love you kind of hit that note at the end. Will ferrell should do all commencement addresses.
