In accordance with the declassified FBI counterintelligence and criminal investigation files, including the codenamed “Rusty Thumbs” and “Freshman Fifteen” operations, and the investigative reports from Axios in late 2020, this series reconstructed the complete process of how Chinese national Fang Fang infiltrated California and Midwestern political circles between 2011 and 2015 on a student visa, as well as how the FBI conducted counterintelligence monitoring, double-agent recruitment, and criminal investigation against her until her hasty return to China. It exposes how the Chinese Communist Party targeted grassroots U.S. politics through unconventional political intervention and infiltration, attempting to erode the integrity of democratic politics.
FBI Declassified Fang Fang Case: The Beginning of a Red Undercurrent (Part 1)
In the second episode, we go back to 2013 when the FBI unexpectedly discovered Fang Fang while monitoring a Chinese consulate diplomat and initiated the secret informant recruitment program codenamed “Rusty Thumbs” in the summer of the same year to launch a shocking counterintelligence operation.
The initial attention from the FBI San Francisco Field Office on Fang Fang did not stem from a direct report on her but was an incidental harvest while monitoring another high-value target.
According to declassified files and statements from intelligence officials, around 2012, the FBI San Francisco Field Office was conducting long-term electronic and physical surveillance on a suspected Ministry of State Security (MSS) intelligence officer from China.
This MSS officer, who was active at the Chinese consulate general in San Francisco, was using the cover of a diplomat to actively engage with political figures at the state and local levels in California, including sending invitations and fully funding their visits to China for official or private purposes.
During the surveillance, FBI agents discovered that this diplomat from the consulate had been meeting with Fang Fang, a “student leader” then attending California State University, East Bay, multiple times in secret and had frequent communications. While interactions between Chinese student association presidents and consulate officials for organizing community events were common, Fang Fang’s unusually close relationship with the consulate set off alarms.
The FBI investigation revealed that Fang Fang’s main intelligence “handlers” in the Bay Area were primarily stationed within China, but the diplomat in the consulate in San Francisco provided her with convenient channels and support for contact locally.
This unusual network convergence prompted the FBI to delve deeper into Fang Fang’s background, uncovering her astonishing family background – both her parents were known intelligence officers in the Ministry of State Security of China. On March 18, 2013, the FBI San Francisco Field Office officially opened a “preliminary investigation” on her, categorizing the case as a counterintelligence search.
Following the opening of the preliminary investigation, the FBI decided to employ “business tactics” – deploying undercover agents to approach Fang Fang in the guise of a private business consulting company to conduct physical and psychological assessments, delineating her real connections with American political figures, official CCP sources, and the national security apparatus of China.
On May 22, 2013, in Las Vegas, Nevada, an undercover agent from the FBI San Francisco Field Office met Fang Fang for the first time through a referral. During the meeting, the undercover agent pitched that the company was looking for a consultant with Chinese connections familiar with local politics. Fang Fang immediately showed a keen interest in joining the company as a contracted consultant.
On June 6, 2013, the San Francisco Field Office drafted a secret electronic communication titled “Rusty Thumbs” (RT) action plan to establish a code name “RT” for Fang Fang in the intelligence network.
This plan outlined three core objectives: to gather more physical and psychological assessment data about RT, determine which valuable American political and social information RT could access, and evaluate her willingness to accept “fee-for-service” tasks, and subsequently turn her into an unwitting double-agent providing CCP intelligence for the U.S.
FBI investigators conducted an extremely detailed psychological analysis and motivation assessment on Fang Fang. In their report, they pointed out that her two core motivations were “money and power.” She was eager to engage in political campaigns, organize student associations and community activities fundamentally to gain a sense of self-worth as a “trusted person and a bridge to power core connections” at the grassroots level. She placed a high value on external image, eager to wear expensive branded clothes and drive a luxury car, indicating a strong financial need for a high-end lifestyle.
The report stated that Fang Fang had strong social skills, a cultured appearance, and conversational agility, but at the same time displayed significant “self-centered and narcissistic traits,” which could pose a potential risk as a reliable intelligence source. For instance, she would boast about her interactions in U.S. politics but belittle her past experiences in China (once stating, “No one cares about my achievements in China”); she took pride in being mistaken as a Shanghainese or Korean instead of from Beijing because she thought Beijing locals were not fashionable.
In mid-June 2013, at a high-end restaurant in San Francisco, the second “developing meeting” took place following the action plan. Fang Fang arrived on time in nearly business-formal attire, displaying a friendly, open, and highly professional attitude. During the dinner, Fang Fang submitted her personal resume and discussed her contracted role in the company with the undercover agent. She expressed willingness to act as a “liaison intermediary” between the company and the CCP government, stating that most of her connections were deeply rooted within the Chinese government, offered to help the company “make more friends in China” at the agent’s expense, attempting to invite these high officials to visit the U.S.
Subsequently, Fang Fang presented two “transactional demands” with strong personal motives, further convincing the FBI that she could be swayed by money and benefits, such as concerns about her F-1 student visa status after graduation. She tentatively asked if the undercover agent’s company could provide her with an official employment letter stating that she was employed there to apply for a Social Security Number (SSN).
Fang Fang also mentioned being invited to attend the upcoming “National Mayors Conference” in Las Vegas, claiming it was a personal invitation from a mayor. However, as she could not afford the travel expenses, she inquired if the company could cover her hotel accommodation and entertainment expenses in Las Vegas. The undercover agent immediately agreed and arranged to meet in Las Vegas.
On June 14, 2013, in Palo Alto, California, Fang Fang signed the FBI’s fictitious company’s “Independent Contract Agreement” and “Confidentiality Agreement” during the third official meeting.
The contract stipulated that Fang Fang’s job responsibilities were to “provide cultural expertise to the company and facilitate contact networks to promote business operations.” The remuneration was $500 basic fee per month, with additional bonuses for outstanding performance, and Fang Fang expressed satisfaction with being paid in cash.
In the documents, FBI agents specifically noted that Fang Fang did not appear “sophisticated” when reviewing the contract involving federal legal responsibilities and the “Confidentiality Agreement” and seemed to have signed without carefully reading the terms.
During the contract signing dinner, fueled by alcohol and excitement from signing the contract, Fang Fang made several overt and overtly threatening statements.
When discussing how to penetrate grassroots politics and manipulate targets, Fang Fang bluntly stated, “using seduction and physical relationships as tools to manipulate and gain the trust of American political figures.” Fang Fang exhibited extreme self-assuredness about her appearance and sexual allure. She unabashedly told the undercover agent, “If I want to, I can use my sexual charm to get close to politicians and mayor teams because I am young and beautiful.”
Fang Fang mentioned that Congressman Swalwell and another candidate had jokingly asked her if she was the “CIA of the CCP” (referring to the Ministry of State Security). She said she had denied it in a joking manner by saying, “MSS officers are either old men or old ladies; how could I, being fashionable, possibly be one?”
She further derogatorily commented, “If the MSS wanted to use sexual seduction to lure American officials, they could simply pay for prostitutes instead of dispatching their own agents.”
Fang Fang also boastfully mentioned her family’s relationship with high-ranking CCP diplomats, recalling how she had sung for the then-Minister of Foreign Affairs at a family gathering in her childhood. However, she later mentioned that about two years ago, the minister and other high-ranking officials resigned due to a scandal involving a questionable relationship with a 40-year-old woman that may have been aimed at extortion.
By March 2014, after a year-long covert operation aimed at turning Fang Fang into a double agent for the U.S., an unexpected turn of events occurred.
On March 11, 2014, the FBI San Francisco Field Office officially circulated a memo requesting the termination of the “Rusty Thumbs” operation. The memo attributed the “failure reasons” to a clear intelligence conclusion: While the operation successfully established contact with Fang Fang and conducted a comprehensive assessment, she displayed a high level of counterintelligence vigilance and boundaries, adamantly refusing to accept any assignments from the FBI that provided substantive commercial intelligence value.
In other words, although Fang Fang was willing to receive the monthly $500 cash reward and superficially introduce some irrelevant local political-business relationships for the undercover agent’s company, once the tasks involved concrete, substantive collection of internal CCP intelligence, she evaded and made excuses.
According to the FBI’s “Domestic Investigation Operations Guide,” the San Francisco Field Office made a C-4 administrative closure on “Rusty Thumbs.” The official conclusion stated: “Reasonable investigations and leads have been exhausted, and to date, the investigation has not uncovered criminal violations or priority-level national security threats.”
However, the conclusion of the counterintelligence recruitment in “Rusty Thumbs” did not mean the FBI’s investigation into Fang Fang’s activities stopped. Six days later, the San Francisco Field Office launched a separate criminal investigation codenamed “Freshman Fifteen,” shifting focus to suspected illegal campaign donations and potential public office benefits exchanges.
On March 17, 2014, based on abnormal money flows and information gathered during the recruitment process, the FBI San Francisco Field Office directly turned its attention to criminal public corruption – initiating the “Freshman Fifteen” criminal investigation concerning Federal Congressman Swalwell and Fang Fang.
Stay tuned for the next episode, where we delve into the investigative storm from 2014 to 2015, uncovering the FBI’s physical surveillance footage at a shopping center in California, the mysterious woman wearing red shoes, and how Fang Fang weaved a network of scandals between the National Mayors Conference and mayors in the Midwest, including the power play of sexual encounters recorded by the FBI and the $1,000 credit card “fishing” campaign.
