Given Facebook's track record of broken promises over privacy, U.S. senators said Tuesday that the social media giant can't be trusted when it comes to plans to launch a digital currency.

"Facebook is dangerous," Sen. Sherrod Brown, D-Ohio, said at a Senate Banking Committee hearing. "Like a toddler who's gotten his hands on a book of matches, Facebook has burned down the house over and over, and called every arson a learning experience."

Twitter is creating a warning label to flag and suppress political tweets that break the platform's rules on acceptable speech. It's a bold step for the company, which has come under sharp criticism for its handling of tweets by major political figures including President Trump.

In one Facebook post, he stands tall in yellow camouflage, decorated with badges. He promises he'll increase the salaries of teachers in Sudan. In another post, he hunches over a fire, cooking food with locals.

Facebook says that by next year people on apps like Whatsapp and Messenger will be able to basically text payments. This news comes as regulators are asking if the tech giant is already too powerful.

The ride-hailing company Uber made its stock market debut on Friday, and promptly saw share prices dip.

Uber priced its shares at $45, the lower end of the possible range, aiming for a total diluted market value of about $82 billion. After a delay of two and a half hours, trading started with the stock at $42, down more than 6 percent over that initial price.

Facebook expects to pay a fine of up to $5 billion in a settlement with federal regulators. The tech giant disclosed that figure in its first-quarter 2019 financial results.

The U.S. has long exported its culture abroad — think Coca-Cola, Hollywood and hip-hop. Facebook was once praised for spreading free-speech values. But the world is pushing back with different values, which Facebook is importing to the U.S. with the company's ban on white extremist content.

Two words for you: flying taxis. That's right. In the not-so-distant future, you'll open your ride-hailing app and, in addition to ground options like car, SUV, scooter or bicycle, you'll see on-demand air flight.

At least that's according to the optimists at South by Southwest, the annual tech-music-film convention in Austin, Texas.

Over the weekend in Austin, Texas, South by Southwest became a major presidential forum. More than half a dozen candidates showed up to the annual music, arts and technology convention. Democrats competed with each other to be the tough-on-tech candidate, a development in line with the party's move to the left but at odds with its reliance on tech donors.

Facebook CEO Mark Zuckerberg promises to bring end-to-end encryption and self-destruct features to Messenger and other Facebook apps, in a move meant to signal the tech behemoth's commitment to privacy. He announced the proposed changes in a a blog post Wednesday.

As Facebook struggles to repair its image after a global privacy scandal, the social media giant is trying to make the platform a place that Mark Zuckerberg says encourages "meaningful interactions between people."

One person who embodies Zuckerberg's message is Lola Omolola, an ebullient 41-year-old Nigerian-American woman who was highlighted at Facebook's annual conference in May.

The U.S. takes credit for creating the Internet, and the European Union seems determined to govern it. On Friday, a sweeping new directive goes into effect called the General Data Protection Regulation, or GDPR. Taken together, its 99 articles represent the biggest ever change to data privacy laws. The new rules have implications for U.S. Internet users too.

Here are answers to three questions you might have about the new law and its potential impacts.

What is GDPR?

Despite criticism for sharing disinformation and sharing people's data, Facebook reported another quarter of record earnings. NPR's Aarti Shahani reports.

Dan Shefet is an unlikely tech revolutionary. He's not a young math geek who builds driverless cars, nor does he promise to make a tech product for the masses. His crusade is different. The 63-year-old year old Shefet has staged an astonishingly effective campaign in Europe to thwart the torrent of fake news and damaging personal attacks that course through the Internet by taking on the tech giants.

(SOUNDBITE OF ULRICH SCHNAUSS' "NOTHING HAPPENS IN JUNE")

It was the summer of 2016, and M was worried her ex-husband was stalking her. She would get out of town and stay with friends. But, as she noted in court documents, her ex seemed to know exactly where she was and whom she visited — down to the time of day and street.

M started to change the way she drove — slowing down, driving in circles — in case a private investigator was following her. She didn't see one. Then she went online and learned about GPS trackers — small devices you can slip into a car to monitor where it goes 24/7. She looked for one and couldn't find any.

Lyft is unveiling a new education program for drivers, offering access to discounted GED and college courses online. The move is an interesting experiment in the gig economy, where a growing class of workers receive zero benefits from a boss and yet competition for their time is fierce.

Many Lyft drivers see their work for the company as a stopgap measure, a flexible way to make money while they try to build a career.

Tucked away in the House and Senate tax bills is a big break for companies that have stockpiled money overseas. The hope is that bringing that cash back to the U.S. will lead to more jobs here. NPR's Aarti Shahani reports.
