Executives from Alphabet Inc. parent Google’s YouTube, Snap Inc. , and TikTok are scheduled to testify Oct. 26 for the next Senate panel inquisition on social media’s impact on kids. Facebook Inc. faced a similar reckoning late last month. Next week’s hearing will be held by Sens. Richard Blumenthal, D-Conn., and Marsha Blackburn, R-Tenn., who chastised Facebook for knowingly allowing policies on Instagram that are harmful to teens following a blockbuster report in the Wall Street Journal. In a subsequent statement Wednesday, Blumenthal demanded that Facebook Chief Executive Mark Zuckerberg and Instagram head Adam Mosseri testify next week.
