NEW YORK (AP) — Democratic presidential candidate Elizabeth Warren on Friday rolled out a proposal to break up the biggest U.S. technology companies, saying they have too much control over the economy and Americans' lives.In her pitch to rein in the influence of tech giants, the Massachusetts senator envisions legislation targeting companies with annual worldwide revenue of billion or more, limiting their ability to expand and forcing parts of Google and Amazon's current business structure to operate as separate entities.As president, Warren said she would pick regulators who would seek to break up what she called "anti-competitive mergers" such as Facebook's recent purchase of Instagram and Amazon's acquisition of Whole Foods.She made the pitch ahead of a rousing town hall appearance Friday in the New York City neighborhood where Amazon recently scrapped plans to open a new headquarters.It's Warren's latest effort to shape the policy agenda for the rest of the Democratic presidential primary, coming after earlier announcements of a "wealth tax" plan on households with high net worth and a universal child care proposal.Her tech agenda, coming at a time of rising public concern about the growing power of the dominant players, could force the rest of her rivals for the 2020 nomination to follow her lead.During remarks before a crowd of more than 1,000 people in Queens, Warren touted elements of her new tech-industry plan as part of her stump speech. She took aim at Amazon's search for lavish economic incentives from cities competing for its headquarters, likening the company's efforts to pit areas against each other to the dystopian film "The Hunger Games.""That's what's wrong with the system. It's not just that big tech companies like Amazon have enormous market power, which they do. They have enormous political power," Warren told the audience, describing the industry's lobbying expenditures as a "good return on investment if they can keep Washington from enforcing the antitrust laws."It remains to be seen whether Warren will introduce legislation in the current Congress aligning with the first element of her plan. A spokeswoman, Kristen Orthman, said a bill introduction was not imminent.Warren's latest policy proposal also promised to be a central element of her scheduled visit Saturday to the South by Southwest conference in Austin, Texas.Sen. Kamala Harris of California represents the tech industry's home state, while Sen. Cory Booker has come under scrutiny for his past ties to tech companies — though he's stepped up his criticism of the industry in recent years.Facebook spokeswoman Monique Hall said the company had no comment on Warren's proposal. Representatives for Google, Amazon, Microsoft and Apple did not immediately respond to a request for comment. 2822

NEW YORK CITY — Snitches get — a quarter of the proceeds?New York City city legislators have proposed a new bill that would allow people in the city to report others for parking illegally and take a cut of the fine.Two Democratic New York City councilmen — Council Speaker Corey Johnson and Stephen Levin — are the primary sponsors of the bill that would create a 5 fine for obstruction of a bike lane, bus lane, sidewalk, cross walk or fire hydrant under certain conditions.The bill would also create a civilian reporting program, essentially allowing passersby to submit complaints — and provide evidence — of a violation to the Department of Transportation. Once the city collects the fine, the complainant gets 25%.If the bill passes, it'll bring new meaning to "if you see something, say something."This story was originally published by Corey Crockett on WPIX in New York City. 894

The beloved comic marks its 70th anniversary this week by donating "Peanuts" murals for kids to paint in 70 children's hospitals around the globe, from Brooklyn to Brazil.

Children and hospital staffers are encouraged to paint the easy-to-follow templates, a diversion that gains even more importance during coronavirus restrictions.Apple+ also announced they are releasing a new series called "The Snoopy Show." "Dive into new adventures with the happy-dancing, high-flying, big-dreaming beagle, who's joined by friends Woodstock and the rest of the Peanuts gang," Apple+ described the upcoming show. 975

New research confirms that temperature and symptom checks miss many coronavirus infections. A study published Wednesday found that these measures failed to detect infections in new Marine recruits before they started training, even after several weeks of quarantine. Many recruits had no symptoms yet still spread the virus. Genetic testing revealed six separate clusters of cases among the recruits.The work has implications for colleges, prisons, meatpacking plants and and other places that rely on symptom screening. Doctors say more COVID-19 testing is needed, especially in younger people who often don't develop symptoms.An estimated 20% of coronavirus infections do not result in symptoms. The good news is those who are asymptomatic generally do not spread the virus as easily as those who have symptoms, according to a University of Minnesota study. 868
