Zuckerberg faces Capitol attack grilling as Biden signals tougher line on big tech

The head of Facebook, and his Google and Twitter counterparts, could face a rough ride at the scene of the insurrectionists' crime

Mark Zuckerberg, the head of Facebook, could be in for a rough ride on Thursday when he testifies to Congress for the first time about the 6 January insurrection at the Capitol in Washington DC and amid growing questions over his platform's role in fuelling the violence.

The testimony will come after signs that the new administration of Joe Biden is preparing to take a tougher line on the tech industry's power, especially when it comes to the social media platforms and their role in spreading misinformation and conspiracy theories.
