Members of the House Bipartisan Privacy Caucus are pressing Facebook to explain what information the social network collects and how long it preserves that data.

In a letter to Facebook CEO Mark Zuckerberg, four lawmakers, including caucus co-chairs Joe Barton, R-Texas, and Ed Markey, D-Mass., say that recent data and privacy breaches have made them become "increasingly concerned that users' personal information could be vulnerable to hackers."

The lawmakers ask Facebook to provide information on what user information it collects and how it is stored. They also ask whether Facebook deletes user information upon request.
