Facebook has had a particularly bad few days, even for a Silicon Valley giant that has been under fire for months. The social network, which was once Silicon Valley’s pride and joy, is now facing a new scandal over data privacy — and the fallout has been intense and keeps widening.

Let’s recap how it all unfolded:

Over the weekend, The New York Times, along with The Observer of London and The Guardian, broke the news that a British political consulting firm, Cambridge Analytica, improperly obtained data on 50 million Facebook users and used it to target messages to potential American voters.

The revelations set off an immediate hue and cry. American and British lawmakers demanded that Facebook explain how the data had been harvested without people being alerted. Senator Amy Klobuchar, a Democrat from Minnesota, pressed Mark Zuckerberg, Facebook’s chief executive, to appear before lawmakers in person. Others have since piled on.
