From Wiki- In April 1987 Reagan appointed Matlock as Ambassador to the Soviet Union. Conditions at the Embassy were tense, as Marine Sergeant Clayton Lonetree had been found to have compromised Embassy security. Within a few months of the Lonetree scandal, all U.S. intelligence assets in the Soviet Union had been exposed. The Americans suspected that the security breach had meant that the Embassy code room was no longer secure and worked frantically to determine how. It was not until 1994 that Aldrich Ames, a mole within the CIA, was caught.[48] Another mole, Robert Hanssen, this time within the FBI, was caught only in 2001.
