Facebook chief executive Mark Zuckerberg will testify before a joint hearing of the Senate Judiciary and Commerce committees on Tuesday, April 10.
Why it matters: Zuckerberg's Senate appearance will come one day before he testifies before the House Energy and Commerce Committee. He'll face tough questions about data privacy and Facebook's role in democracy in both sessions.
