Mohamedou Ould Slahi—Central Intelligence Agency relationship

Mohamedou Ould Slahi’s relationship with the Central Intelligence Agency was shaped by secret transport, prolonged interrogation, and a consequential absence of information-sharing. On November 28, 2001, a CIA rendition plane took him from Mauritania to a prison in Amman, Jordan, where Jordanian intelligence services questioned him for seven and a half months. On July 19, 2002, another CIA plane retrieved him and delivered him to Bagram Air Base in Afghanistan. These transfers made the agency a direct link in the chain that carried him from Mauritanian custody into a hidden international detention route and, ultimately, toward Guantánamo.## Transfer into Secret Custody Slahi’s disappearance followed his voluntary return to Mauritanian police questioning. He had driven himself to the station on November 20, 2001; eight days later, instead of remaining in the custody his family believed to be Mauritanian, he was secretly transported by the CIA to Jordan. His family was not told where he had gone. For almost a year, relatives thought he was being held in Mauritania, and his oldest brother, Hamoud, regularly brought clean clothes and money for his meals to a Nouakchott security prison. Prison officials accepted the money while concealing that Slahi was no longer there. The family learned from a German magazine in October 2002 that he had been taken to Guantánamo, by then after transfers through Jordan and Afghanistan. The account establishes the concealment surrounding Slahi’s location, while distinguishing that fact from the specific actions of the local prison officials who misled his relatives.

The route placed the CIA inside a wider U.S.-directed system of detention and interrogation. The account describes Slahi’s ensuing journey as an approximately twenty-thousand-mile passage through four countries over eighteen months, with American participation along the way and the United States determining its direction. The CIA’s role in the two flights was distinct: it moved him from Mauritania to a Jordanian prison, then retrieved him from Amman and delivered him to Bagram. After two weeks of questioning at Bagram, the U.S. military transferred him with thirty-four other prisoners to Guantánamo, where they arrived on August 5, 2002. The account thus separates the CIA’s rendition flights from the later military transport rather than treating every stage as a single agency operation.## The Amman Interrogation and the Information Gap The reported focus of the questioning in Jordan remained the Millennium Plot. Slahi later told a review board that the Jordanians were investigating his part in that plot and were especially concerned about it. The available account does not establish that the CIA’s interrogation produced evidence connecting him to the September 11 attacks or another terrorist plot. Instead, it highlights what happened to the information after his time in Amman: the CIA apparently did not provide the Guantánamo prosecutors with intelligence from that interrogation.

That absence became significant when Lieutenant Colonel Stuart Couch was assigned to build a case against Slahi. Couch said that the CIA showed him no intelligence reports of its own; most of the reports the agency did share came from Slahi’s later Guantánamo interrogation. Couch was contemplating a capital case and said that evidence connecting Slahi to the September 11 attacks would have mattered to the prosecution’s decision. He reasoned that the CIA must either have obtained as much information as it could or found that the information did not establish Slahi’s significance, before transferring him into U.S. military control at Bagram. This was Couch’s inference, not a disclosed account of the CIA’s internal reasoning.

The broader record sharpened the question without resolving it. Ahmed Ressam, who had cooperated with U.S. authorities and named many people in terrorism investigations, conspicuously did not implicate Slahi, according to Judge James Robertson’s habeas opinion. The account notes that the CIA would have known whether Jordanian interrogators had uncovered links to the Millennium Plot, the September 11 attacks, or other plots, but that no Amman interrogation material apparently reached the prosecutors. The gap therefore concerns both the outcome of the Jordanian questioning and the agency’s decision—or failure—to convey its results to the military case team. The evidence presented does not establish what the CIA knew internally or why it did not share such material.

Secrecy, Accountability, and the Public Record

The secrecy of the transfers shaped what Slahi’s family could know and what later investigators could establish. In early 2002, his relatives did not know he was in Jordan, and few people knew the United States was conducting a rendition and detention program with the cooperation of foreign intelligence services. The account places Mauritania within that network of cooperation, while noting the political sensitivity of U.S. counterterrorism collaboration there. It also describes a constitutional protection against extraditing Mauritanian citizens, making the secret removal of Slahi politically and legally consequential. The passage raises the implications of that protection but does not claim that a public extradition process occurred.

The public account of the CIA’s detention practices is partial. A 2004 CIA inspector general report included a passage stating that the agency had a particular interest in detainees who, if not kept isolated, might disclose the circumstances of their detention. The passage offers institutional context for why secrecy mattered; it does not by itself establish a specific order concerning Slahi. Similarly, later editorial annotations to the manuscript are based on contextual reading and public materials, including declassified government records, litigation, journalism, and official investigations. The editor explicitly declined to reconstruct classified text or claim access to the unredacted manuscript. That distinction matters: documented transfers and the family’s prolonged misinformation can be described, while gaps in the record remain gaps.

The relationship is therefore marked not only by movement across borders but by divided custody and divided knowledge. The CIA arranged Slahi’s transfers into and out of Jordan; Jordanian intelligence conducted the stated interrogation there; U.S. military custody followed at Bagram and Guantánamo. Yet the agency’s role did not yield a visible body of its own intelligence in the prosecutor’s files described by Couch. The same operation that made Slahi’s location inaccessible to his family also left later readers with an incomplete account of what the CIA learned. His route is clear; the agency’s full knowledge and the reasons for its information-handling remain unresolved.
