Members of the U.S. Senate Committee on Commerce, Science, and Transportation's Subcommittee on Consumer Protection, Product Safety, and Data Security used a hearing with Facebook whistleblower Frances Haugen to lament the need for Congress to act on federal privacy legislation, The Wall Street Journal reports. Sen. Amy Klobuchar, D-Minn., explicitly called for the drafting of a comprehensive privacy law during the hearing while characterizing Haugen as "the catalyst for that action." Haugen added that simply updating existing U.S. privacy laws "will not be sufficient."
