Twitter is still trying to figure out who is behind that high-profile hack.Tweets were sent out from verified accounts, saying they would send money to anyone who sent cash to a bitcoin address.Experts say whoever is behind it possibly used "social engineering," sending phishing emails, texts or phone calls to Twitter employees to get gain access. 357

Trudging forward in the sweltering sun, thousands of migrants left the Mexican city of Tapachula on Monday and continued their trek toward the U.S. border.There seemed to be little organization as the migrants streamed north -- and plenty of peril.Cars whizzed by long lines of people walking on a highway. One man fell hard from the back of a flatbed. A group of migrants said they had witnessed a child run over by a truck.Scenes from the 2,000-mile journey thousands are making to get to the U.S. borderMexican and Honduran authorities confirmed Monday that a 25-year-old Honduran national participating in the caravan had died."I deeply lament the death of a 25-year-old Honduran man, who was participating in the migrant caravan. He lost his life when he fell off a trailer that was moving," Mexico's Interior Secretary Alfonso Navarrete Prida tweeted. Another Honduran national was confirmed dead Saturday, when he fell off a pick-up truck.On Monday, the majority of migrants made their way on foot. But some also flagged down cars and trucks passing by and piled onto any vehicle that would take them.The highway behind the passing migrants was littered with plastic bottles, juice boxes and Styrofoam plates, resembling the scene of a marathon that has just ended.But for this group -- which U.N. officials estimate numbers more than 7,000 -- the marathon is far from over. 1389

US President Donald Trump says China has agreed to cut tariffs on cars it imports from the United States.Trump made the announcement in a tweet late Sunday in the United States, saying Beijing will "reduce and remove" the tariffs, which currently stand at 40%. He didn't specify when the change would happen or what the new tariff level would be.Chinese Foreign Ministry spokesman Geng Shuang declined to comment Monday on Trump's statement, referring questions to "the relevant authorities." The Chinese Commerce Ministry, which typically makes announcements regarding tariffs, didn't respond to a faxed request for comment.Trump's tweet comes after he and Chinese President Xi Jinping agreed on Saturday to hold off on further tariffs in the trade war between the two countries for the time being. But the Chinese government has made no mention of cutting car tariffs as a result of the meeting between the two leaders in Buenos Aires.Xi announced in a speech in April that China would cut tariffs on imported cars this year. His government followed through on that promise three months later, reducing them from 25% to 15%.But just days later, it imposed new additional tariffs of 25% on American-made passenger vehicles, one of the groups of products it targeted early in the trade warwith the United States.The move has hurt the profits of major automakers like BMW (BMWYY) and Daimler (DDAIF), the owner of Mercedes-Benz. The German companies both ship SUVs to China from manufacturing plants in the United States.Shares in BMW jumped more than 6% on Monday morning in Frankfurt following Trump's tweet, while Daimler's stock leaped more than 5%.Tu Le, the head of research firm Sino Auto Insights, highlighted the lack of specifics in Trump's tweet. 1804

TUCSON, Arizona — As teachers vote on a potential walk out their employers are trying to figure out what to do if that happens.Tucson Unified School District Superintendent Gabriel Trujillo said Tuesday a prolonged walk out that affects final exams could jeopardize high school graduation schedules.He says TUSD is trying to find a way to keep schools open and busses running so students who rely on schools for meals can eat. That would include a skeletal bus schedule and at least some staff coming to work. “Schools physically would be open, but instructional services would be closed. There would be no classes running,” Trujillo said.He said the district does not a have substitute pool large enough to fill classrooms in the case of a walk out. 763

Vice President Joe Biden told reporters this week during a campaign stop in Pennsylvania that he would take a potential coronavirus vaccine even if it costs him the election.Biden’s comments come as questions are arising over the timing of a coronavirus vaccine as President Donald Trump continues to hint that a vaccine could be ready before Election Day – a claim many top health experts say is highly unlikely."We're going to have a vaccine very soon... maybe even before a very special date, you know what date I'm talking about,” Trump said on Monday.Biden in Pennsylvania expressed concern that Trump is undermining trust in the public health system. But conceded he too is ready for a vaccine.“One of the problems is the way he's playing with policy,” Biden said. “He says so many things that aren't true, I'm worried if we do have really good vaccine, people will be reluctant to take it. So he's undermining public confidence, but pray God, we have it. If I could get a vaccine tomorrow, I'd do it. If it cost me the election, I'd do it. We need a vaccine. We need it now."Although several vaccine candidates are in Phase 3 studies, leading public health experts suggest a vaccine would most likely be approved around the end of the year or early in 2021.In late August, the CDC told states to begin to prepare distributing a vaccine by Nov. 1. But Surgeon General Jerome Adams said that just because states will be ready to help distribute a vaccine on Nov. 1 does not mean a vaccine will be ready by then."We've always said that we're hopeful for a vaccine by the end of this year or the beginning of next year,” Adams told Good Morning America."We want to make sure states are available to distribute it," he added.Dr. Anthony Fauci, in an interview with NBC News last week, agreed that he believes a “safe and effective” vaccine could be ready by the end of the year."I believe that by the time we get to the end of this calendar year, that we will feel comfortable that we do have a safe and effective vaccine," he told NBC News. 2051
