In an op-ed for The Wall Street Journal, U.S. President Joe Biden reiterated calls for U.S. Congress to pass comprehensive federal privacy legislation. Among Biden's "three broad principles for reform" against Big Tech, he said "serious federal protections for Americans’ privacy" topped the list. "That means clear limits on how companies can collect, use and share highly personal data," Biden said, adding "it's not enough" for companies to simply disclose data collection practices. Biden also urged limits on targeted advertising and stringent rules to safeguard children's privacy.
