Mark Zuckerberg just switched from "Maybe" to "Attending" to a congressional hearing. 

The House Energy and Commerce Committee announced on Wednesday morning that the Facebook founder will be testifying on April 11, at 10 a.m. ET. Facebook and Zuckerberg faced massive pressure to answer to lawmakers in the wake of its Cambridge-Analytica scandal. A whistleblower had revealed that Facebook's lax data policy allowed for the UK-based analytics firm to use unauthorized information from 50 million users.
