Leaders of the House Energy and Commerce Committee, which oversees technology issues, are calling on Mark Zuckerberg to testify on the Cambridge Analytica data-harvesting scandal.

Why it matters: The calls are growing for Zuckerberg to answer Congress's questions publicly about how user data was accessed improperly by a data analytics firm. Zuckerberg gave a handful of media interviews Wednesday evening — during which he stated a willingness to talk to Congress.
