Aldrich Ames, CIA agent who spied for Moscow for almost a decade, dead at 84

CIA turncoat Aldrich Ames, who betrayed Western intelligence assets to the Soviet Union and Russia in one of the most damaging intelligence breaches in U.S. history, has died in a Cumberland, Md., prison. He was 84.

A spokesperson for the U.S. Bureau of Prisons confirmed Ames died Monday.

Ames admitted being paid $2.5 million US by Moscow for U.S. secrets from 1985 until his arrest in 1994. He admitted disclosing the identities of 10 Russian officials and one eastern European who were spying for the United States or the United Kingdom.

His betrayals are blamed for the executions of Western agents working behind the Iron Curtain and were a major setback to the CIA.

He pleaded guilty without a trial to espionage and tax evasion and was sentenced to life in prison without parole. Prosecutors said he deprived the U.S. of valuable intelligence material for years.

He professed “profound shame and guilt” for “this betrayal of trust, done for the basest motives,” money to pay debts. But he downplayed the damage he caused, telling the court he did not believe he had “noticeably damaged” the United States or “noticeably aided” Moscow.

“These spy wars are a sideshow which have had no real impact on our significant security interests over the years,” he told the court in a matter-of-fact tone.

In a jailhouse interview with the Washington Post the day before he was sentenced, Ames said he was motivated to spy by “financial troubles, immediate and continuing.”
