After voters in three states went to the polls on Tuesday to cast ballots in the 2020 Democratic nominating race, former Vice President Joe Biden took another giant leap toward becoming the Democrats' 2020 standard-bearer. The results of Tuesday's three-state primary will help Biden expand his lead over Sen. Bernie Sanders. The former vice president is projected to win the primaries on Tuesday in Arizona, Florida and Illinois.As votes were tabulated on Tuesday, Biden made a pitch to Sanders supporters, whom he'll need to win over in order to become president. "Senator Sanders and I may disagree on tactics, but we share a common vision — for the need to provide affordable health care for all Americans to reducing income inequality to taking on climate change," Biden said."Senator Sanders and his supporters have brought remarkable passion and tenacity to these issues, and together, they have shifted the fundamental conversation in the country."Sanders opted to speak earlier in the evening, addressing his plans on addressing the coronavirus crisis. As far as Sanders' plans moving forward, that is unknown. Both Sanders and Biden have been off the campaign trail for the last week, opting to host virtual town hall events for supporters. Sanders has used large rallies to create buzz for his campaign. With 93% of the vote in from Florida, Biden is winning with 61% of the vote, compared to 22% for Sen. Bernie Sanders. Biden also has a substantial lead in Illinois, up 59-36 over Sanders with 76% of the vote in. Biden has now won 19 states. A total of 441 delegates up for grabs on Tuesday between the states of Arizona, Florida and Illinois.Last night, Ohio announced it is postponing its presidential primary amid fears of the spread of coronavirus. Biden entered Tuesday with 898 delegates as Sen. Bernie Sanders trails with 745 delegates. To win the nomination, 1,991 delegates are required. 1922

A teenager has been arrested on suspicion of attempted murder after a boy was thrown from the 10th floor at the Tate Modern gallery in central London on Sunday, the city's Metropolitan Police said.The 6-year-old was found badly injured on a fifth-floor roof and was taken to a hospital by a helicopter, police said.Officers initially said the boy was in critical condition. In an update on Monday, they said he was in "critical but stable condition." They added the boy's family was being supported by police.Police said the 17-year-old male suspect had remained with members of the public on the 10th-floor viewing platform and was taken into police custody."There is nothing to suggest that he is known to the victim," the statement added.The London Ambulance said it received the first call about the incident at 2:40 p.m. local time (9:40 a.m. ET)."We sent two ambulance crews, an incident response officer, a medic in a response car and an advanced paramedic to the scene. We also dispatched London's Air Ambulance and our Hazardous Area Response Team," a spokesperson for the service said in an emailed statement.Nancy Barnfield, from Manchester, was on the 10th floor of the gallery with her two sons at the time of the incident.She said she heard a loud bang as she was walking away, and saw several people restraining a young man whom she said she previously noticed acting suspiciously.She said the man, who appeared to be 19 to 21 years old, looked very calm and was not fighting back.Police said a number of people have given them witness statements.Visitors to the gallery reported on social media that the landmark building, on the south bank of the Thames, was locked down as a result of the incident. The Metropolitan Police later allowed visitors to leave. The gallery was closed to visitors following the incident. Security guards at the scene told CNN it was unlikely to be reopened on Sunday.The Tate Modern was the most visited tourist attraction in the United Kingdom in 2018, according to the Association of Leading Visitor Attractions. The group said the gallery welcomed 5.9 million people last year. 2137

Airlines in multiple countries have suspended the use of Boeing's new 737 MAX 8 aircraft over concerns about its safety, after an Ethiopian Airlines flight of the same model crashed Sunday killing all 157 on board.Flight ET302 to Nairobi had just taken off from the Ethiopian capital of Addis Ababa Sunday when it reported technical problems and asked for permission to turn back. It crashed shortly afterwards.As the crash investigation got underway, the Civil Aviation Administration of China ordered Monday that all domestic Boeing 737 MAX 8 jets be out of the air by 6 p.m. local time, due to its principle of "zero tolerance for safety hazards."China has one of the world's largest fleets of Boeing 737 MAX 8, operating 97 of the planes, according to Chinese state-run media.The move was followed by an announcement from Ethiopian Airlines that the carrier had grounded its fleet of Boeing 737 MAX 8 jets as an "extra safety precaution." Cayman Airways also said on Monday it was grounding both of its "new Boeing 737 MAX 8 aircraft ... until more information is received."Sunday marked the second time in less than six months that a new Boeing aircraft crashed just minutes into a flight. A Lion Air Boeing 737 MAX 8 flight went down over the Java Sea last October, killing all 189 people on board.Both crashes are under investigation and there is no evidence of a link between the two, but similarities in the incidents have prompted caution among some airlines."Given in both air crashes, the aircrafts were newly delivered Boeing 737 MAX 8, and both accidents occurred during the take-off, they share certain similarities," the Chinese administration said in a statement. It added that it would contact Boeing and the US Federal Aviation Administration to confirm "flight safety" issues before allowing the planes to fly again.Mary Schiavo, a CNN aviation analyst and the former Inspector General of the US Transportation Department, called the two incidents "highly suspicious.""Here we have a brand-new aircraft that's gone down twice in a year. That rings alarm bells in the aviation industry, because that just doesn't happen," she said.State-owned Ethiopian Airlines is one of Africa's leading aviation groups, and the continent's largest carrier by number of passengers.The Kenyan and Ethiopian governments announced a joint disaster response team on Monday to investigate the crash. Kenya's Cabinet Secretary of Transport James Macharia described it as a "very complex investigation."In a statement Sunday, Boeing said it was "deeply saddened" to hear about the loss of life in the Ethiopian Airlines plane crash."A Boeing technical team will be traveling to the crash site to provide technical assistance under the direction of the Ethiopia Accident Investigation Bureau and US National Transportation Safety Board," the statement said.Investigations ongoing after crashThe Ethiopian Airlines flight to Nairobi, in Kenya, lost contact with authorities shortly after takeoff at 8.44 a.m. local time, just minutes after it left Bole International Airport.Tewolde GebreMariam, Ethiopian Airlines CEO, said at a press conference Sunday that the pilot had reported technical difficulties and had been given clearance to return to the Ethiopian capital.An eyewitness told CNN they saw smoke coming from the plane before it crashed on Sunday.GebreMariam said a routine maintenance check hadn't revealed anything before takeoff. The pilot was a senior Ethiopian Airlines employee who had flown more than 8,000 hours and had an "excellent flying record," he added."As it is a fresh incident, we have not been able to determine the cause. As I said, it is a brand new airplane with no technical remarks, flown by a senior pilot and there is no cause that we can attribute at this time," GebreMariam said.Speaking on Monday, Kenyan Transport Secretary Macharia said relatives of the victims would be given "the utmost attention," including accommodation and flights to Ethiopia, if necessary.The US National Transportation Safety Board said on Sunday it would be sending a team of four to assist in the investigation into the crash.CNN aviation expert Richard Quest said while a "final determination" on the cause of the crash might be years away, information from the flight recorders should be retrieved within a matter of weeks.Global disasterCitizens of 35 countries were among the 157 people killed in Sunday's crash, including 32 Kenyans, 18 Canadians, nine Ethiopians and eight passengers each from China, Italy and the United States.The United Nations has announced 19 of their staff members were among the dead, including employees of the World Food Programme, the Office of the High Commissioner on Refugees and the Food and Agriculture Organization.Not all victims have been named, but some details have been released.The Ethiopian government expressed its "deepest condolences to the families," in a statement from the office of Prime Minister Abiy Ahmed. 4985

Airfares are almost certain go up this summer. Troubles with the Boeing 737 Max are part of the reason.The grounding of the Boeing 737 Max jet took 371 planes out of service worldwide for an indefinite period of time. Boeing also halted deliveries of new jets that could have been in service by the time the peak summer season arrived. Discount European carrier Ryanair had been awaiting its first 737 Max when deliveries were halted.Among 737 Max's largest customers are discount airlines, like Southwest in the United States and Norwegian Air in Europe. Those carriers put pressure on fares, forcing other airlines to offer more seats at lower prices to compete for leisure travelers. Fewer flights by discount carriers mean less competition for other carriers, and less incentive to offer lower-priced seats on their planes."I think it certainly has the ability to pressure fares higher as we get into the busy summer months," said Helane Becker, airline analyst for Cowen.Uncertainty over when the Boeing 737 Max will be back in service has led airlines to cancel hundreds of flights a day all the way into August. Southwest canceled flights through August late last week, and American Airlines, the world's largest carrier, did the same on Sunday. United Airlines, the third US airline with a version of the 737 Max in its fleet, has canceled flights through early July.United on Tuesday trimmed its estimate for how much its capacity will grow this year. It expects to grow by up to 5% growth, down from its earlier forecast of 6%. It also said it expects sales from passenger fares to be up 2.5% in the April through June period.Summer is the peak travel season for airlines. They put as many planes in service as they can, which means fewer extra planes will be available to fill in for the missing 737 Max jets."All the airlines have some extra planes at any period of time. But in the summer the system is strained more tightly," said Philip Baggaley, the lead credit analyst for transportation companies for Standard & Poor's.The 737 Max problems aren't the only reason fares will be higher this summer. A strong US economy, with near record low unemployment has increased demand for travel. And higher jet fuel prices limit routes that airlines are willing to fly. "It's tough to disentangle the impact of the 737 Max from the other factors," said Baggaley.When jet fuel is lower, airlines will add flights on routes where they might not otherwise be profitable, which adds to passenger choices and can push down fares. The opposite happens when fuel prices are higher. Fuel prices are about 20% above where they were a year ago, and prices are expected to climb higher in the next three months.Europe doesn't have as strong an economy as the United States, but a number of budget airlines have gone out of business in the last six months, including Wow Air, Primera Air and FlyBMI. That means less fare competition, allowing fares at other carriers to rise.All of Boeing's Max planes were grounded worldwide last month after a 737 Max jet flown by Ethiopian Airlines pilots crashed in that country, killing everyone aboard. It was the second fatal crash involving a Max in recent months. A Lion Air flight crashed in October.Investigators believe the crashes are tied to an automatic safety feature of the new jet that forced its nose down.It's unclear when Boeing will get approval for a 3449

A new study shows that gastric bypass surgery for weight loss is working just as well in adolescents as it does for adults, if not better.Dr. Thomas Inge, chief of pediatric surgery at Children's Hospital (Aurora) Colorado who led the study, says teens are able to reverse the health conditions that are associated with obesity, such as Type 2 Diabetes and high blood pressure, much more efficiently.The results show early intervention can lead to better long-term results, he said. But it's not for everyone — about 8 percent of American teenagers would qualify."It's not just 30 pounds overweight, it's more — more like 75 to 100 pounds overweight, with an identifiable complication of the obesity," Inge said.Some doctors are hesitant to try the procedure and are concerned about the surgical risk, he said. They want to make sure the teens get enough nutrients with the new restrictive diet.Inge said he hopes the research will lead to more access for teenagers who want to explore the option. He posted a video about it that has had more than 8.5 million views.Sixteen-year-old Dustin Vogelbacher says he is glad he had the surgery. His mom, Stacey Force, was against it at first."It worried me a little bit because it's such a lifetime change that at 16, 17, life is so different than it's going to be you know in your 20s in your 30s," she said.Eventually the family supported it. Vogelbacher says he wants to inspire others: He posted a video about it that has had more than 8.5 million views."It was the best decision of my life," Vogelbacher said."Stay positive and love your life because you only got one. So it's live life to the fullest," he said. 1672
