In a September 2015 interview with Michael Isikoff, Fiorina said that, in the weeks following the September 11 terrorist attacks in 2001, she received a phone call from Michael Hayden, then the director of the National Security Agency, asking her assistance in providing HP computer servers to the NSA for expanded surveillance. Hayden confirmed that he had made the request for HP servers as part of Stellar Wind, a 2001–2007 NSA warrantless surveillance program, but the details were not revealed to Fiorina at the time. Fiorina "acknowledged she complied with Hayden's request, redirecting trucks of HP computer servers that were on their way to retail stores from a warehouse in Tennessee to the Washington Beltway, where they were escorted by NSA security" to the agency's Fort Meade headquarters. In 2015, Fiorina said: "I felt it was my duty to help, and so we did," adding, "They were ramping up a whole set of programs and needed a lot of data crunching capability to try and monitor a whole set of threats. ... What I knew at the time was our nation had been attacked." Hayden also requested that Fiorina provide advice to the agency "on how the CIA could maintain its undercover espionage mission in a culture of increasing government leaks and demands for greater public accountability and openness." According to Fiorina, she advised the agency to be "as transparent as possible, about as much as possible".
