She was cleared when her boss was identified as the security leak, and she returned to work in November 2002. By then, she said, her reputation was ruined, her career derailed.

Chiang believes she came under suspicion because she is Chinese American. “That’s the only explanation I can derive …,” Chiang said.

A former FBI agent cleared of suspicion of spying for the Chinese said in remarks published today that she came under scrutiny because of racial discrimination. Rita Chiang, 53, retired last year, ending a 21-year-career during which she matched wits with Chinese agents in the world of counterintelligence. The Taiwan-born Chiang was hired by the FBI in 1984 after becoming a U.S. citizen. On Jan. 14, 2002, Chiang was stripped of her badge and gun and escorted out of the West Los Angeles FBI office. FBI Director Robert S. Mueller suspected she was a mole for Chinese intelligence and, after she failed a polygraph test, ordered her suspended with pay while she was investigated.
