Facebook employees got to ask questions, but not of Mark Zuckerberg

Grewal, a former federal magistrate judge, was also the author of Facebook's Friday statement that it was suspending Cambridge Analytica.

Facebook declined to comment on the meeting or who attended, but said in a statement:

Mark, Sheryl and their teams are working around the clock to get all the facts and take the appropriate action moving forward, because they understand the seriousness of this issue. The entire company is outraged we were deceived. We are committed to vigorously enforcing our policies to protect people’s information and will take whatever steps are required to see that this happens.
