I was inside the CIA’s Langley, Va., headquarters on Sept. 11, 2001. Like all Americans, I was traumatized, and I volunteered to go overseas to help bring al-Qaeda’s leaders to justice. I headed counterterrorism operations in Pakistan from January to May 2002. My team captured dozens of al-Qaeda fighters, including senior training-camp commanders. One of the fighters whom I played an integral role in capturing was Abu Zubaida, mistakenly thought at the time to be the third-ranking person in the militant group.

By that May, the CIA had decided to torture him. When I returned to CIA headquarters that month, a senior officer in the Counterterrorism Center asked me if I wanted to be “trained in the use of enhanced interrogation techniques.” I had never heard the term, so I asked what it meant. After a brief explanation, I declined. I said that I had a moral and ethical problem with torture and that — the judgment of the Justice Department notwithstanding — I thought it was illegal.

Unfortunately, there were plenty of people in the U.S. government who were all too willing to allow the practice to go on. One of them was Gina Haspel, whom President Trump nominated Tuesday as the CIA’s next director.

Putting Haspel in charge of the CIA would undo attempts by the agency — and the nation — to repudiate torture. The message this sends to the CIA workforce is simple: Engage in war crimes, in crimes against humanity, and you’ll get promoted. Don’t worry about the law. Don’t worry about ethics. Don’t worry about morality or the fact that torture doesn’t even work. Go ahead and do it anyway. We’ll cover for you. And you can destroy the evidence, too.

Described in the media as a “seasoned intelligence veteran,” Haspel has been at the CIA for 33 years, both at headquarters and in senior positions overseas. Now the deputy director, she has tried hard to stay out of the public eye. Mike Pompeo, the outgoing CIA director and secretary of state designee, has lauded her “uncanny ability to get things done and inspire those around her.”

I’m sure that’s true for some. But many of the rest of us who knew and worked with Haspel at the CIA called her “Bloody Gina.”

The CIA will not let me repeat her résumé or the widely reported specifics of how her work fit into the agency’s torture program, calling such details “currently and properly classified.” But I can say that Haspel was a protege of and chief of staff for Jose Rodriguez, the CIA’s notorious former deputy director for operations and former director of the Counterterrorism Center. And that Rodriguez eventually assigned Haspel to order the detruction of videotaped evidence of the torture of Abu Zubaida. The Justice Department investigated, but no one was ever charged in connection with the incident.
