Barton: Next Congress will address online privacy

The comments came after Facebook responded to a letter from Barton and Rep. Edward MarkeyEdward (Ed) John MarkeyDemocrats search for 51st net neutrality vote Overnight Regulation: Dems claim 50 votes in Senate to block net neutrality repeal | Consumer bureau takes first step to revising payday lending rule | Trump wants to loosen rules on bank loans | Pentagon, FDA to speed up military drug approvals Dems say they have 50 votes in Senate to overrule net neutrality repeal MORE (D-Mass) about online privacy issues. Markey also said he will keep working on the issue.

"With privacy legislation under consideration by the Energy and Commerce Committee, I will continue to work with my colleagues to ensure that Facebook personal user data isn’t siphoned off and sold to a data broker who cannot be unfriended,” he said.

Facebook has said it did not sell user data. Rather, third party applications shared a limited amount of user information with marketers.

Facebook spokesman Andrew Noyes responded to the remarks on Wednesday.

"We were happy to provide Reps. Markey and Barton with answers to any questions they had and look forward to working with them in the future. Facebook has never sold and will never sell user information," he said.

"We also have zero tolerance for data brokers because they undermine the value that users have come to expect from Facebook," he said. "To restate our policy, developers may not pass any data from Facebook to data brokers, and we are now including anonymous identifiers in this protected category of Facebook data."
