Sen. Dianne Feinstein, D-Calif., is asking the CIA to declassify agency documents related to CIA Deputy Director Gina Haspel’s involvement in the spy agency’s interrogation program after the Sept. 11, 2001 terror attacks.

“As we move forward with the nomination process for Ms. Haspel, my fellow senators and I must have the complete picture of Ms. Haspel’s involvement in the program in order to fully and fairly review her record and qualifications,” Feinstein wrote in a letter to Director Mike Pompeo and Haspel.
