The top Republican on the House Oversight and Reform Committee asked executives of Capital One bank and Amazon Web Services for a briefing on the theft of data on 106 million credit card applicants and customers, citing rising privacy concerns and the digital giant’s government contracts.

“Because Amazon Web services will provide the trusted Internet connection and cloud support for the 2020 Census and could potentially run the Department of Defense’s Joint Enterprise Defense Infrastructure cloud computing system, the committee may carefully examine the consequences of this breach,” U.S. Rep. Jim Jordan, an Ohio Republican, said in a letter to Amazon CEO Jeff Bezos obtained by the Washington Examiner. Reps. Mark Meadows and Michael Cloud, of the subcommittees on government operations and economic policy, also signed the letter.
