Facebook’s chief executive, Mark Zuckerberg — or perhaps more accurately, members of his staff — are going to be very busy getting through a stack of homework.

He also said he would get back to Mr. Grassley on how many outside developers his team has audited to make sure they are following Facebook’s rules.
