Tech CEOs grilled over role in Capitol attack as protesters mock them with giant cutouts

Protesters outside the Capitol denounced the platforms as Facebook, Twitter and Google heads questioned by Congress

The CEOs of America's biggest technology companies faced a grilling on Thursday from Congress about the 6 January insurrection at the Capitol, as protesters outside the hearing denounced the platforms for playing a role in fueling the violence.

The marathon, six-hour hearing saw the three most powerful men in tech - Sundar Pichai of Google, Mark Zuckerberg of Facebook and Jack Dorsey of Twitter - testify before two committees of the House of Representatives on social media's role in promoting extremism and misinformation.
