The U.S. Postal Service said that it will review if any of its employees used their government email addresses to access the infidelity website Ashley Madison. The department, along with its internal affairs watchdog, will review whether any employees violated federal policies by using their government email on the site. "We are looking into this matter and will follow our existing administrative process if misconduct is identified," stated U.S. Postal Service spokesman Dave Partenheimer. The site was hacked last month and last week, hackers posted the site's user base online.
