Facebook CEO Mark Zuckerberg, facing a backlash over user data that ended up in the hands of third-party tech firms and possibly Russian operatives seeking to sow discord in the 2016 election, heads to Capitol Hill Tuesday and Thursday to answer for his companies actions before two separate congressional committees.

He is expected to testify, based on prepared remarks, on Facebook’s privacy policies, the Cambridge Analytica situation wherein a reported 87 million users had their personal information scrubbed, and just how much Russia used the platform to create chaos and discord in their efforts to undermine the American democratic process.

Zuckerberg, who apologized in a call with reporters recently, will meet with a joint hearing of the Senate Judiciary and Senate Commerce, Science, and Transportation committees at 2:15 pm ET on Tuesday. Then on Wednesday, he’ll sit before the House Energy and Commerce Committee at 10 am ET.

“Our joint hearing will be a public conversation with the CEO of this powerful and influential company about his vision for addressing problems that have generated significant concern about Facebook’s role in our democracy, bad actors using the platform, and user privacy,” said senator John Thune of South Dakota in a statement.
