A former State Department employee pleaded guilty Wednesday to conspiring with Chinese intelligence agents for providing them with internal government documents.

Candace Claiborne, 63, failed to disclose her repeated contacts with two agents of China’s intelligence service, who gave her tens of thousands of dollars of gifts over five years.

The gifts included cash, international travel and vacations, tuition at a Chinese fashion school, a fully furnished apartment, and a monthly stipend, according to prosecutors.

In exchange, Claiborne, who was employed as an office management specialist, gave the agents copies of internal State Department documents on U.S. economic strategies, and visits by dignitaries between the two countries, among other topics.

She then misled FBI and State Department investigators about her contacts with the agents and urged a co-conspirator to dispose of evidence connecting her to the agents.

Claiborne joined the State Department in 1999, serving in posts in China, Sudan, and Iraq until she returned to the U.S. in 2015. She held a top secret security clearance during her employment.

She was first paid by a Chinese agent in 2011, who wired her almost $2,500 in exchange for information on “what types of pressures the United States government planned to place on the Chinese government if certain expectations were unmet” after the U.S.-Sino Strategic and Economic Dialogue wrapped up between the two countries, according to the criminal complaint.

Prosecutors said Claiborne knew the consequences of sharing information with the agents, but was motivated by the financial rewards.

When it came time to renew her security clearance in 2014, Claiborne “deliberately excluded” her contacts with the Chinese agents, the criminal complaint said. She also omitted the contacts to investigators while she continued to communicate with the agents about additional benefits and tried to hide evidence of their agreement.

The FBI sent an undercover agent, who posed as a Chinese intelligence officer, to her home in Washington, D.C. Claiborne invited the undercover agent into her home, but never reported the contact to the U.S. government, despite the government’s requirement to do so.

Claiborne was arrested in March 2017. She pleaded guilty to one count of conspiracy to defraud the United States and faces up to five years in prison.

“Candace Claiborne was entrusted with Top Secret information when she purposefully misled federal investigators about her repeated interactions with foreign contacts which violated her oath of office as a State Department employee,” Assistant Director in Charge Nancy McNamara of the FBI's Washington Field Office said in a statement.
