Facebook CEO Mark Zuckerberg was on Capitol Hill Wednesday to testify before the the House Financial Services Committee about Libra, Facebook's controversial cryptocurrency plan. At least, Libra was theoretically his reason for being in Washington, DC. Once he was in the hot seat, however, lawmakers pinned him down with questions about basically everything, making clear just how much ire the ostensible social network now draws at the highest level.

The hearing, titled "An Examination of Facebook and its Impact on the Financial Services and Housing Sectors," ran for more than five hours as representatives pressed Zuckerberg on a variety of topics. Many of the questions seemed to leave the CEO flustered as members of the committee dug in.
