Uber is taking heat over its handling of rider and driver data. Photo: Kirsty Wigglesworth / AP

Senators are targeting Uber after the company said that 57 million accounts belonging to drivers and customers had been breached by hackers.

Why it matters: It's just the latest regulatory headache for Uber, which still has an IPO in its sights.

Democratic Sen. Mark Warner said in a letter to the company's CEO that "Uber's conduct raises serious questions about the company's compliance with relevant state and federal regulations." Warner has been a key critic of the tech industry of late, especially over allegations Russian operatives used online platforms to interfere with the 2016 election.

Sen. John Thune, the chamber's third-highest ranking Republican and the chair of the Commerce Committee, joined three others on a separate letter saying that it was a "a serious incident that merits further scrutiny" and that a payment to the hackers was especially "troubling." That letter also includes Orrin Hatch, the top Republican on the Senate Finance Committee. Both letters request responses from the company.

Facebook seeks fountain of youth

Data: Piper Sandler Taking Stock With Teens Study; Chart: Axios Visuals

Facebook CEO Mark Zuckerberg on Monday said that the company is pivoting its strategy to focus on young adults, following reports that teens have fled its apps.

Why it matters: A series of stories based on leaked whistleblower documents suggest the company sees the aging of its user base as an existential threat to its business.

Too big to cover alone: Newsrooms team up

News outlets are increasingly willing to work together on big, multifaceted stories — including this week's reporting on leaked documents from a Facebook whistleblower.

Why it matters: Collaborative efforts help bring more resources to bear on complex stories, some of which require a global reporting effort. But they require high degrees of coordination, and competition can sometimes get in the way.

Axios-Ipsos poll: Confidence in Biden COVID recovery tumbles

Data: Axios/Ipsos poll; Chart: Kavya Beheraj/Axios

Confidence in President Biden's ability to rescue the economy from COVID-19 has dropped since January, even as Americans' faith rises in his ability to make the vaccine widely accessible, according to the latest installment of the Axios/Ipsos Coronavirus Index.

Why it matters: It's Democrats and independents driving the declining economic confidence, from 52% of all U.S. adults at the start of his presidency to 44% now. Their softening faith could hinder Biden's ability to lead and hurt Democrats' position heading into the 2022 midterms.
