This follows Facebook CEO Mark Zuckerberg's marathon 10 hours of testimony to Senate Judiciary Committee, Senate Commerce Committee and House Energy and Commerce Committee over two days this week. He gave details about how Cambridge Analytica, a political data analysis consultancy, was reportedly able to buy Facebook profile data for more than 87 million users, and he offered apologies for what he called Facebook's breach of trust.

During the hearings, he also addressed everything from concerns about political censorship to questions about upcoming European privacy regulations to conspiracy theories about whether his company's app is surreptitiously listening through your phone to better serve ads (he reassured the committee it's not true).
