Kara Swisher on Big Tech’s big problem

Renowned tech journalist Kara Swisher has no doubt that social media companies bear responsibility for the January 6th pro-Trump riots at the Capitol and will likely be complicit in the civil unrest that may continue well into Biden's presidency. It's no surprise, she argues, that the online rage that platforms like Facebook and Twitter intentionally foment translated into real-life violence. But if Silicon Valley's current role in our national discourse is untenable, how can the US government rein it in? That, it turns out, is a bit more complicated. Swisher joins Ian Bremmer on GZERO World.
