The CEOs of Twitter, Facebook and Google are facing a grilling by Republican senators making unfounded allegations that the tech giants show anti-conservative bias.The Senate Commerce Committee has summoned Twitter CEO Jack Dorsey, Facebook’s Mark Zuckerberg and Google’s Sundar Pichai to testify for a hearing Wednesday. The executives agreed to appear remotely after being threatened with subpoenas.With the presidential election looming, Republicans led by President Donald Trump have thrown a barrage of grievances at Big Tech’s social media platforms, which they accuse without evidence of deliberately suppressing conservative, religious and anti-abortion views.The chorus of protest rose this month after Facebook and Twitter acted to limit dissemination of an unverified political story from the conservative-leaning New York Post about Democratic presidential nominee Joe Biden, an unprecedented action against a major media outlet. The story, which was not confirmed by other publications, cited unverified emails from Biden’s son Hunter that were reportedly disclosed by Trump allies.Beyond questioning the CEOs, senators are expected to examine proposals to revise long-held legal protections for online speech, an immunity that critics in both parties say enables the companies to abdicate their responsibility to impartially moderate content.The Justice Department has asked Congress to strip some of the bedrock protections that have generally shielded the tech companies from legal responsibility for what people post on their platforms. Trump signed an executive order challenging the protections from lawsuits under the 1996 telecommunications law.“For too long, social media platforms have hidden behind Section 230 protections to censor content that deviates from their beliefs,” Sen. Roger Wicker, R-Miss., the Commerce Committee chairman, said recently.In their opening statements prepared for the hearing, Dorsey, Zuckerberg and Pichai addressed the proposals for changes to so-called Section 230, a provision of a 1996 law that has served as the foundation for unfettered speech on the internet. Zuckerberg said Congress “should update the law to make sure it’s working as intended.”“We don’t think tech companies should be making so many decisions about these important issues alone,” he said, approving an active role for government regulators.Dorsey and Pichai, however, urged caution in making any changes. “Undermining Section 230 will result in far more removal of online speech and impose severe limitations on our collective ability to address harmful content and protect people online,” Dorsey said.Pichai urged lawmakers “to be very thoughtful about any changes to Section 230 and to be very aware of the consequences those changes might have on businesses and consumers.”Assistant Attorney General Stephen Boyd told congressional leaders in a letter Tuesday that recent events have made the changes more urgent. He cited the action by Twitter and Facebook regarding the New York Post story, calling the companies’ limitations “quite concerning.”The head of the Federal Communications Commission, an independent agency, recently announced plans to reexamine the legal protections, potentially putting meat on the bones of Trump’s order by opening the way to new rules. The move by FCC Chairman Ajit Pai, a Trump appointee, marked an about-face from the agency’s previous position.Social media giants are also under heavy scrutiny for their efforts to police misinformation about the election. Twitter and Facebook have slapped a misinformation label on content from the president, who has around 80 million followers. Trump has raised the baseless prospect of mass fraud in the vote-by-mail process.Starting Tuesday, Facebook was not accepting any new political advertising. Previously booked political ads will be able to run until the polls close next Tuesday, when all political advertising will temporarily be banned. Google, which owns YouTube, also is halting political ads after the polls close. Twitter banned all political ads last year.Democrats have focused their criticism of social media mainly on hate speech, misinformation and other content that can incite violence or keep people from voting. They have criticized Big Tech CEOs for failing to police content, homing in on the platforms’ role in hate crimes and the rise of white nationalism in the U.S.Facebook, Twitter and YouTube have scrambled to stem the tide of material that incites violence and spreads lies and baseless conspiracy theories.The companies reject accusations of bias but have wrestled with how strongly they should intervene. They have often gone out of their way not to appear biased against conservative views — a posture that some say effectively tilts them toward those viewpoints. The effort has been especially strained for Facebook, which was caught off-guard in 2016, when it was used as a conduit by Russian agents to spread misinformation benefiting Trump’s presidential campaign.The unwelcome attention to the three companies piles onto the anxieties in the tech industry, which also faces scrutiny from the Justice Department, federal regulators, Congress and state attorneys general around the country.Last week, the Justice Department sued Google for abusing its dominance in online search and advertising — the government’s most significant attempt to protect competition since its groundbreaking case against Microsoft more than 20 years ago.With antitrust in the spotlight, Facebook, Apple and Amazon also are under investigation at the Justice Department and the Federal Trade Commission.___Follow Gordon at https://twitter.com/mgordonap. 5687

The first experimental COVID-19 vaccine in the U.S. is on track to begin a huge study next month to prove if it really can fend off the coronavirus, while hard-hit Brazil is testing a different shot from China.Where to do crucial, late-stage testing and how many volunteers are needed to roll up their sleeves are big worries for health officials as the virus spread starts tapering off in parts of the world.Moderna Inc. said Thursday the vaccine it is developing with the National Institutes of Health will be tested in 30,000 people in the U.S. Some will get the real shot and some a dummy shot, as scientists carefully compare which group winds up with the most infections.With far fewer COVID-19 cases in China, Sinovac Biotech turned to Brazil, the epicenter of Latin America’s outbreak, for at least part of its final testing. The government of S?o Paulo announced Thursday that Sinovac will ship enough of its experimental vaccine to test in 9,000 Brazilians starting next month.If it works, “with this vaccine we will be able to immunize millions of Brazilians,” said S?o Paulo′s Gov. Joao Doria.Worldwide, about a dozen COVID-19 potential vaccines are in early stages of testing. The NIH expects to help several additional shots move into those final, large-scale studies this summer, including one made by Oxford University that’s also being tested in a few thousand volunteers in Brazil.There’s no guarantee any of the experimental shots will pan out.But if all goes well, “there will be potential to get answers” on which vaccines work by the end of the year, Dr. John Mascola, who directs NIH’s vaccine research center, told a meeting of the National Academy of Medicine on Wednesday.Vaccines train the body to recognize a virus and fight back, and specialists say it’s vital to test shots made in different ways — to increase the odds that at least one kind will work.Sinovac’s vaccine is made by growing the coronavirus in a lab and then killing it. So-called “whole inactivated” vaccines are tried-and-true, used for decades to make shots against polio, flu and other diseases — giving the body a sneak peek at the germ itself — but growing the virus is difficult and requires lab precautions.The vaccine made by the NIH and Moderna contains no actual virus. Those shots contain the genetic code for the aptly named “spike” protein that coats the surface of the coronavirus. The body’s cells use that code to make some harmless spike protein that the immune system reacts to, ready if it later encounters the real thing. The so-called mRNA vaccine is easier to make, but it’s a new and unproven technology.Neither company has yet published results of how their shots fared in smaller, earlier-stage studies, designed to check for serious side effects and how well people’s immune systems respond to different doses.Even before proof that any potential vaccine will work, companies and governments are beginning to stockpile millions of doses so they can be ready to start vaccinating as soon as answers arrive.In the U.S., a program called “Operation Warp Speed” aims to have 300 million doses on hand by January. Under Brazil’s agreement with Sinovac, the Instituto Butantan will learn to produce the Chinese shot.___AP journalist Marcelo Silva de Sousa contributed to this report.___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

The bull market turns 3,453 days old on Wednesday. It's the longest period of uninterrupted gains in American history.The remarkable run began on March 9, 2009, in the ashes of the Great Recession and the scariest financial crisis since the 1930s. The slow-but-steady economic recovery, coupled with unprecedented aid from the Federal Reserve, catapulted the Dow from around 6,500 to nearly 26,000 today. The S&P 500 has quadrupled from its 2009 low of 666. And market darlings like Netflix and Amazon have skyrocketed much further.The bull market narrowly survived countless panic attacks from crisis-scarred investors along the way. There was the downgrade of America's credit rating in 2011, the feared collapse of the euro, China's alarming economic slowdown and the dramatic crash in oil prices.Yet each scare failed to derail the steady rise of the economy and corporate profits that has underpinned Wall Street's record-breaking run. There were close calls, but the S&P 500 never dropped 20%, the trigger for a new bear market. 1050

The cost of education can last a lifetime, as many people into their 50s and 60s are finding out.According to Federal Reserve, 2.8 million people in the U.S. over the age of 60 are sitting on some amount of student debt, a number that quadrupled from 700,000 in 2005 and continues to grow.“This is really a sledgehammer against the older generation in more ways than one,” says Alan Collinge, creator of online advocacy group for borrowers Student Loan Justice.Collinge has been campaigning for change surrounding laws for student loans since 2005, after trying to figure out a way to pay off his own crippling college costs.“It’s a really devastating phenomenon, and I’m seeing it destroy, literally wreck, families across the country,” Collinge says. In 2018, Americans over the age of 50 owed more than 0 billion in student loans, up from billion in 2004, according to the Federal Reserve.And most can’t afford to pay, forcing retirees to continue to work well past retirement age.“The problem has become exponentially worse since we began this fight 13 years ago,” he says.In Collinge’s group, he hears stories from people ages 18 to 80 years old, who can hardly afford to live, let alone retire.“The federal government can and does garnish Social Security from seniors as a result of their student loans, so we’re hearing stories from people who at the end of the month they’re unable to buy medicine even unable to pay their rent,” Collinge says, “What kind of country does this to their senior people?”On top of that, Collinge says more people in their 50s and 60s are taking out Parent Plus loans to help their children and grandchildren pay for college, which adds to the financial burden.“This is a nationally threatening phenomenon,” he said. Through his advocacy group, he tries to offer help and resources to folks who are struggling. He’s currently on a road tour talking to legislators around the country, encouraging them to reform borrower laws, expand their rights and get colleges to crack down on sky-high tuition costs.“Student loans are the only loans in the country not subject to bankruptcy, why is that? The numbers are just getting so astonishing now, I can only hope that the new Congress puts this issue front and center and doesn’t get distracted by the palace intrigue because this is a problem affecting real people it just won’t wait any longer.” 2413
