WASHINGTON – U.S. Sens. John Thune (R-S.D.) and Bill Nelson (D-Fla.), who respectively serve as the chairman and ranking member of the Senate Committee on Commerce, Science, and Transportation, pressed Facebook CEO Mark Zuckerberg today for answers following a report in the New York Times that Facebook offered numerous mobile device manufacturers special access to private user information.

Citing ongoing efforts by the committee to oversee Facebook data privacy and security practices, the letter seeks details from Zuckerberg about his congressional testimony related to user control of personal information, efforts by Facebook to ensure business partner compliance with privacy policies, data storage and retention practices, disclosures to the Federal Trade Commission, and the identities of mobile device manufacturers who partnered with Facebook to receive special access.

The letter gives Zuckerberg a June 18 deadline to answer.  Click here for a copy of the letter.

Zuckerberg has not yet submitted responses to written follow-up questions from his appearance before a joint April hearing of the Senate Commerce and Judiciary committees.
