 The scooter-sharing startup Lime continues to clash with its suppliers amid questions about the safety of its scooters.Chinese company Okai is pushing back on claims that it's the source of flawed Lime scooters.Earlier this month, Lime said it removed all of its scooters manufactured by Okai following reports that the baseboard where users stand can snap in half and endanger riders. Some riders have suffered injuries, and an Okai scooter may have contributed to a fatality. Lime uses scooters from multiple manufacturers, but doesn't reveal exactly how many.In late October, Lime stated the baseboard on its Okai models could break if ridden off a curb at high speeds.Okai said Friday Lime's claims are "groundless" and the faulty scooters come from another supplier."We feel it necessary to make cautions to the public on the credibility of such statements made by Lime," Okai said in a statement sent to CNN Business on Friday. "Obviously, Lime has other suppliers whose scooters broke."Lime declined to comment on whether it has recalled scooters from other manufacturers.Photos on social media and in news reports revealed Lime scooters with broken floorboards -- some of which match images of the scooter model Okai says it provided to Lime. But not all looked the same. The Okai model has a distinct set of lights and screws, the manufacturer said in its statement.Okai said it sold 32,000 scooters to Lime, but the company has not revealed how many scooters it has removed from streets. When it recalled some scooters over battery concerns earlier this year, the issue impacted less than 0.01% of its fleet, Lime said.The company said it is working with the US Consumer Product Safety Commission to investigate its Okai scooters.In 2017, Lime launched as LimeBike, a dockless bikesharing startup. But this year it shifted its focus to scooters after Bird, a Santa Monica startup, pioneered a popular scooter-sharing service. Lime has since raised hundreds of millions of dollars, including from Uber. Lime operates in 10 countries and more than 85 US cities.Scooters have been shown to reduce car trips, earning praise from environmentalists and city experts. But safety questions have followed the company's rapid expansion. In September, a Dallas man died shortly after a crash while riding a Lime scooter. Police discovered the scooter was broken in half, but the company hasn't said if the man was riding an Okai scooter.Along with fellow Lime supplier Ninebot, Okai is calling on scooter companies to do more to protect scooters from the wear-and-tear of daily use."It is the operator's responsibility to ensure proper and prompt management and maintenance of the scooters it puts into the co-sharing market," Okai said.Lime has already taken some steps to tackle safety concerns. It announced a million program to distribute 250,000 helmets and educate riders on safety practices. Lime recently unveiled a new scooter with safety improvements, such as larger wheels, intended to better handle potholes and uneven roads.Companies are racing to meet demand and expand to new cities.But the Silicon Valley-backed companies have grown at a?breakneck pace, which has drawn criticism for introducing problems at a scale that wouldn't occur with steadier growth. Some view scooters as clutter because they're sometimes parked incorrectly, such as blocking sidewalks.According to Tony Ho, vice president of business development at the Chinese company Ninebot, which makes a majority of the shared scooters in use worldwide, the scooter-sharing industry is so new that issues continue to pop up.He said Ninebot plans to release a new model later this year that's better designed for harsh conditions. Shared scooters are typically ridden a half-dozen times a day on roads of varying quality, and in inclement weather. Scooters are often thrown to the ground, or tossed in the back of trucks to be charged. And minor cracks can expose components, leading to malfunctions."There's room to improve in how to operate, and how to train chargers," Ho said of the scooter-sharing startups. "This is almost like a new test for us. The product needs to sustain a real industrial type of environment."Segway is also shifting the battery in its scooters to the baseboard. This will lower the center of gravity, making them less likely to tip over and expose riders to head injuries."It's gonna be a beast," Ho said of the new scooter. 4558

(AP) — It could be a landmark election year for the legal marijuana industry. Voters in four states could approve broad legal marijuana sales, as the push for legalization continues across the US. The contests will take place in vastly different regions — New Jersey, Arizona, South Dakota and Montana. If approved in a sweep, it would highlight how public acceptance of cannabis is cutting through geography, demographics and politics. The most closely watched race is New Jersey, which if approved could prompt New York, Pennsylvania and other Northeast states to follow. Meanwhile, voters in conservative Mississippi will consider competing proposals that would legalize medicinal marijuana. 702

(AP) — The first report cards of the new school year are arriving with a lot more Fs than usual, and it’s not just parents who are getting distressed. School districts from coast to coast have reported the number of students failing classes has risen by as many as two or three times — a sign of the struggles many students are having with distance learning. English language learners, those with disabilities, and other disadvantaged students have been at particular risk.Educators see a number of factors at play: Students learning from home skip assignments — or school altogether. RELATED: Rise in 'F' grades at some North County schools spark virtual learning concernsInternet access is limited or inconsistent, making it difficult to complete and upload assignments.In response schools have been ramping up outreach efforts, prioritizing the return of struggling students for in-person learning and in some cases changing grading policies and giving students more time to complete assignments. 1007

 President Donald Trump's travel ban is throwing up road blocks for a US citizen who needs a bone marrow transplant that could save his life.Maziar Hashemi, 60, was diagnosed with myelodysplastic syndrome, a type of blood cancer, in September. His doctors say the only treatment that can cure his cancer is a bone marrow transplant. Maziar Hashemi's brother, Kamiar Hashemi, is a 100% bone marrow match to Maziar, but he lives in Iran.Iran is one of eight countries subject to restrictions on their citizens entering the United States as part of a Trump administration policy implemented in December. Under this policy, people from Iran -- both immigrants and visitors -- are prevented from entering the United States unless they are students, scholars or have an exchange visitor visa. Iranians can still apply for visas, but many have been denied since the ban took effect, although waivers can be granted.Maziar Hashemi came to the United States to study civil engineering in 1975 and he is a naturalized citizen. He works as a civil engineer, but has not been working since October because he has been in and out of the hospital. His brother and sister still live in Iran.Kamiar Hashemi applied for a visa to come to the United States in February so he could have the bone marrow transplant surgery at the hospital in Massachusetts where his brother is being treated. His visa was denied the same day he had a visa application interview at a US Embassy in Armenia. After he received the rejection, he submitted an application for a visa waiver.Almost two months later, the Hashemis still don't know if Kamiar Hashemi will be able to travel to the United States. Maziar Hashemi is undergoing his fourth round of chemotherapy this week, and his doctors have scheduled a bone marrow transplant surgery for April 27. Right now, Maziar's son Robert is planning to give his bone marrow for his father's surgery, but Robert is only a 50% match."They are not waiting for my brother anymore," Maziar Hashemi said. "They are proceeding with the 50% match procedure because I get sick often and my body cannot take it anymore. I need to have this transplant done."Hashemi has pursued other options. Be the Match, an organization that helps facilitate bone marrow transplants in the United States and around the world, says it offered to help the Hashemi family. The organization was planning to send Hashemi's brother from Iran to a hospital in India where he'd undergo the bone marrow extraction procedure. Then Be The Match would transport those stem cells back to the United States. But the organization's legal team said the stem cells would be considered an Iranian export, and under current US sanctions against Iran, that would be illegal.The Treasury Department, which oversees trade sanctions, declined to comment when CNN asked about the Hashemi case.Hashemi also has a sister, but she had cancer last year, so she is not eligible to give Maziar a transplant.In his waiver application to the embassy, Kamiar Hashemi included letters from doctors at Massachusetts General Hospital in Boston and from Massachusetts Rep. Michael Capuano, a Democrat. Maziar Hashemi has hired attorney Mahsa Khanbabai to help with the process."He submitted materials right then and there," Khanbabai said of Kamiar's interview. "They denied the case but said we'll review your waiver application, and that's what's been pending all this time."One-hundred percent matches are rare. Only 30% of patients find matching donors within their families, according to research compiled by the Institute of Justice. Maziar Hashemi's doctor, Zachariah Defilipp, wrote, "A perfect match will provide the ability for a safe transplant as there is a higher likelihood that cells will not be recognized as foreign," in the letter he submitted with Kamiar's visa waiver application.Khanbabai said it's unclear if the waiver would be approved by the State Department in Washington or by officials in the US Embassy in Armenia. She is helping the Hashemis submit paperwork and liaise with the embassy, but she said suing the State Department is still an option they are considering."We could try to file suit with the State Department for not adjudicating the waiver, because it's still pending," she said. "It is something that we're keeping in mind."CNN contacted the State Department to ask about the case and was referred to the Treasury Department, which had no comment. 4462
