WASHINGTON â The CEOs of social media giants Facebook, Twitter and Google faced a grilling March 25 as lawmakers tried to draw them into admitting responsibility for helping fuel the January insurrection at the U.S. Capitol and rising COVID-19 vaccine misinformation. In a hearing by the House Energy and Commerce Committee, lawmakers pounded Facebook CEO Mark Zuckerberg; Sundar Pichai, the Indian American CEO of Google, which owns YouTube; and Twitter chief Jack Dorsey over their content policies, use of consumersâ data and media use by young children. Republicans raised long-running conservative grievances, unproven, that the platforms are biased against conservative viewpoints and censor material based on political or religious viewpoints.
