Here are all the questions Mark Zuckerberg couldn't answer during this week's congressional hearings

In the span of two days, Facebook CEO Mark Zuckerberg answered questions from 44 senators from two committees and 55 representatives on the House Committee on Energy and Commerce in two separate hearings that went for nearly five hours each.

He was answering questions about the role Facebook played in various data-privacy scandals and how it can address those issues.

Zuckerberg had been training for weeks to face the three congressional committees, but his talking points didn't prepare him to answer every question that came his way — some required specific figures or precise explanations that he wasn't able to provide on the spot.

Even when prodded, Zuckerberg was careful not to promise a response, addressing questions he was unsure of with some variation of "If you'd like, I can have my team follow up with you after this."

Here are some things Zuckerbergs team will need to come back to senators with:

Sen. Chuck Grassley

Rep. Jan Schakowsky
Rep. John Sarbanes
Rep. Adam Kinzinger
Rep. Ray Luján
Rep. Bill Johnson
Rep. Scott Peters
Rep. Debbie Dingell
Rep. Ryan Costello

In addition to statistics and explanations, Zuckerberg told a few senators and representatives that his team would circle back to conversations about data-privacy legislation like the Honest Ads Act (Klobuchar), the My Data Act (Sen. Richard Blumenthal), the Consent Act (Sen. Ed Markey), the Broswer Act (Rep. Marsha Blackburn and Rep. Leonard Lance), and the Secure and Protect Americans' Data Act (Rep. Jan Schakowsky).

Sen. Thom Tillis asked that during Facebook's investigation Zuckerberg go back to "the first known high-profile national campaign that exploited Facebook data," but didn't require him to follow up.

Others requested future discussions on the following:

Sen. Lindsey Graham
Sen. Amy Klobuchar
Sen. Cory Booker
Sen. Maggie Hassan
Sen. Shelley Moore Capito and Rep. Buddy Carter
Sen. Shelley Moore Captio, Rep. Morgan Griffith, Rep. Bill Johnson, Rep. Dave Loebsack.
Sen. Todd Young
Rep. Frank Pallone
Rep. Anna Eshoo
Rep. G. K. Butterfield
Rep. G. K. Butterfield
Rep. Peter Welch
Rep. Richard Hudson
Rep. Buddy Carter

The record will be open for 14 days after the Senate hearing and for 10 days after the House hearing, meaning senators and representatives will still be able to submit written questions. Zuckerberg can make corrections to his testimony during this time too.
