WASHINGTON (AP) — The National Security Agency is reviewing its decision to allow a top official to work part time for a cybersecurity firm that is pitching its services to the financial sector, the agency said on Friday.

NSA’s chief technical officer, Patrick Dowd, was given permission to work up to 20 hours a week at IronNet Cybersecurity, a private firm. The company was founded by Keith Alexander, a retired Army general who used to run the NSA and the U.S. Cyber Command.
