The CIA's Deepest Betrayal: Aldrich Ames and Nine Years of Soviet Espionage
How a counterintelligence officer sold America's secrets to the KGB for over $2 million, compromising more than 100 operations and costing lives.
Published June 6, 2025

On April 16, 1985, Aldrich Ames, a CIA counterintelligence officer with 31 years of service, walked into the Soviet Embassy in Washington, D.C., and offered secrets to the KGB. What began as a calculated scheme to solve his financial troubles became a nine-year espionage operation that would rank among the most damaging intelligence breaches in American history.
Ames held a position of extraordinary trust. As a counterintelligence officer in the Soviet and East European Division, and later as counterintelligence branch chief for Soviet operations from September 1983 to April 1985, he had access to some of America's most closely guarded intelligence. His role meant he knew the identities and locations of virtually every CIA and FBI source operating against the Soviet Union.
When he approached the KGB, Ames didn't hesitate. He specifically requested a meeting with a Soviet diplomat named Chuvakhin, demonstrating the deliberateness of his approach. The KGB received him eagerly. By May 17, 1985, Ames had received his first payment: $50,000. It was the beginning of a financial relationship that would net him more than $2 million over the next nine years.
Timeline
The espionage begins
In April 1985, Aldrich Hazen Ames begins passing classified information to the Soviet Union. The exact date in April is not verified.
Ames arrested in Arlington, Virginia
On February 21, 1994, Aldrich Hazen Ames is arrested outside his residence in Arlington, Virginia, ending the espionage activity.
Ames pleads guilty
On April 28, 1994, Aldrich Ames pleads guilty at the U.S. District Court for the Eastern District of Virginia in Alexandria. Rosario Ames likewise pleads guilty.
Sentence handed down: life without parole
Aldrich Ames is sentenced to life imprisonment without the possibility of parole. Rosario Ames is sentenced to 63 months in prison. The exact sentencing date is not separately verified from the guilty plea.
Aldrich Ames dies in prison
On January 5, 2026, Aldrich Hazen Ames dies while serving his life sentence in federal prison.
Ames' initial motivation was straightforward: money. Buried in personal debt and financial troubles, he framed his first disclosure as a one-time con game. But the opportunity proved too lucrative to abandon. What followed was a systematic betrayal of American intelligence assets conducted through dead drops—a tradecraft method of leaving documents and receiving cash at predetermined locations—and periodic meetings with KGB handlers.
The damage was catastrophic. Ames compromised the identities of virtually all CIA and FBI sources he knew to be operating against the Soviet Union. He identified more than 10 top-level intelligence assets, including double agents Gennady Varenik and Dmitri Polyakov. He also disclosed the identities of 10 Russian officials and one East European who were spying for the United States or Great Britain. In total, he compromised at least 100 American intelligence operations.
The human cost was severe. At least 10 U.S. intelligence sources were executed as a direct result of Ames' betrayals. Among those he compromised was Sergey Federenko—an asset Ames later claimed to consider a friend, yet whose identity he disclosed despite acknowledging the risk.
Ames' espionage continued even after the Soviet Union's collapse in 1991. He seamlessly transitioned from working with the KGB to working with Russia's successor intelligence service, the SVR, demonstrating that his loyalty was always to money rather than country. He operated from CIA headquarters in Langley, Virginia, and later from the agency's Rome station, moving between postings while secretly serving Russian intelligence.
It wasn't until 1994 that Ames' nine-year run ended. Federal investigators closed in, and on April 28, 1994, both Aldrich and his wife Rosario—who had actively participated in the espionage by handling payments and messages—pleaded guilty to espionage-related charges. Aldrich also pleaded guilty to tax evasion.
In court, Ames professed what he called "profound shame and guilt," acknowledging his conspiracy with Soviet and Russian intelligence services and his provision of a "huge quantity" of information on U.S. foreign, defense, and security policies. Yet his contrition rang hollow when he characterized Cold War espionage as a mere "sideshow" with no real impact on American security—a remarkable claim given the operational damage and loss of life his betrayals had caused.
The court showed no mercy. Ames received a life sentence without the possibility of parole. His wife Rosario received 63 months—five years and three months—in prison. Aldrich Ames remained incarcerated until his death in prison on January 5, 2026, at age 84, having spent more than three decades behind bars for one of the intelligence community's greatest security failures.
Ames' case would later be examined alongside that of FBI agent Robert Hanssen, arrested in 2001 for similar espionage activities, cementing the 1980s and 1990s as a period of profound vulnerability within American intelligence.
