A top lawmaker in Congress is questioning whether Facebook allowed two Chinese telecommunications firms with alleged ties to their country’s government to harness data about the social network’s users, potentially subjecting their personal information to new privacy and security risks.

The red flags raised by Sen. Mark R. Warner (D-Va.) on Monday stem from revelations that Facebook struck special data arrangements with roughly 60 device makers including Apple, HTC and Samsung over the past decade, possibly without Facebook users’ knowledge.
