Facebook has signaled that CEO Mark Zuckerberg will testify before Congress by discussing the details of the appearance with lawmakers, according to a person familiar with the conversations.

Three congressional committees have invited Zuckerberg to testify, including the Senate Judiciary Committee at an April 10 meeting about data privacy. It is unclear how many hearings Zuckerberg will attend, and of which committees.
