AT&T’s chief executive, Randall Stephenson, attacked the Justice Department’s lawsuit to block its merger with Time Warner, saying that a combined company would be no different from the Silicon Valley giants that make and distribute video content. As the last witness for the defense in the Justice Department’s legal battle against AT&T’s $85.4 billion deal to buy Time Warner,  Stephenson portrayed the 140-year-old phone giant as being in an existential crisis and in need of the deal with Time Warner to compete against tech companies.

Facebook outlined its data collection practices. According to Product Management Director David Baser, some third-party websites and apps send data about their users to Facebook, regardless of whether those users have Facebook profiles. In return for that information, Facebook helps those websites serve up relevant ads or receive analytics that help them understand how people use their services. The company gets this data from websites and apps that let people share or like posts using Facebook plugins, or log into the website with their Facebook accounts.

Economist Carl Shapiro said his analysis of AT&T's purchase of Time Warner shows that US consumers could together pay an additional $571 million in the year 2021 if the deal is approved.

"The merger will in fact harm consumers and the harm is significant in terms of the dollar amount," Shapiro testified.

Facebook trumpeted the deletion of hundreds of pages and accounts run by the Internet Research Agency, the Kremlin-linked troll army that has sought to meddle in U.S. politics. But of the five examples of deleted accounts Facebook provided the public, two had links to the troll army that should have been obvious to the social networking company months ago.
