Lawmakers who met with Facebook CEO Mark Zuckerberg on Monday said they found him “personable” and “forthright” but still expect to have plenty of questions for him when he testifies this week.

Why it matters: Tomorrow is a big test for Zuckerberg, who has never appeared before Congress, and for lawmakers, who have never engaged this publicly with the issues plaguing Facebook and other online platforms.
