On June 14, 2013, a Chinese student named Fang Fang signed an independent contractor agreement in Palo Alto. The company agreed to pay her $500 a month, in cash, to “provide cultural expertise and facilitate liaison contacts.” She also signed a non-disclosure agreement. Both documents carry her signature. The company didn’t exist.
It was a front run by undercover FBI employees, and the file it went into was codenamed RUSTY THUMBS.
The contract sits in 147 pages of FBI records that the White House’s Government Transparency Task Force released in August, under a declassification memorandum dated March 23, 2026. Most coverage at the time focused on what former Rep. Eric Swalwell told agents about his relationship with Fang, who went by Christine. We read the two packets in date order. Read that way, they show the FBI trying to recruit her and dropping the attempt, then spending three years on a corruption case that cleared the congressman. It ended with a decision not to charge her at all.
The files are back in the news for a reason. Last week, three House committee chairmen asked Nvidia’s Jensen Huang to brief them on his dealings with Alice Huang, a Megaspeed executive they describe as a publicly reported Chinese intelligence asset. The intelligence about her hasn’t been released. The Fang file is the most complete public record of how the FBI has handled a suspected intelligence asset with access to a powerful American.
RUSTY THUMBS, the recruitment that didn’t take
The San Francisco field office opened a preliminary investigation on March 18, 2013. By then, according to its operational plan dated June 6, agents believed Fang had “suspected MSS ties,” a reference to China’s Ministry of State Security. The same plan said both her parents were classified as “known MSS intelligence officers.” An undercover employee had met her in Las Vegas on May 22 and found her “amenable” to working for a notional company. The plan’s stated goal was to see whether she could report on Chinese influence campaigns aimed at U.S. officials.
The meeting notes read like a character study. Agents described her as motivated by “money and power,” noted “egotistical/narcissistic traits,” and recorded that she ordered the most expensive item on the menu. At a dinner documented on June 7, she talked at length about Swalwell’s re-election campaign, which she said was short of money. She told the undercover employee she couldn’t donate herself because she was a foreign national, but suggested his clients could, given Swalwell’s seats on the Homeland Security and Science committees. The agents’ note says she called it a good way to create influence with him.
At a later meeting, documented on June 19, she told the undercover employee that Swalwell and a political candidate had each said, jokingly, that she was suspected of ties to the “Chinese CIA.” She signed the contract at that meeting. The undercover employee told her it wouldn’t be wise to write the letter she wanted for her school so she could get a Social Security card.
It didn’t last.
A closing request dated March 11, 2014, says she was “ultimately unwilling to accept commercialized tasking” that was useful to the bureau. It concluded that the investigation “did not identify a criminal violation or a priority threat to national security.” The memo said a “more overt approach” might work instead. A January 2015 memo shows that a counterintelligence investigation “closely associated” with the operation was still open.
FRESHMAN FIFTEEN, the case against the congressman
Six days after the recruitment file closed, on March 17, 2014, the same field office opened an assessment of Swalwell himself. Its opening memo, dated June 10, 2014, lists possible bribery, conspiracy and campaign finance charges. It says internships in Swalwell’s offices were “promised in exchange for campaign contributions,” some of them routed through conduits to hide foreign money. The case was marked a “sensitive investigative matter” because the subject was a sitting member of Congress. The FBI sent that memo to the Justice Department’s Public Integrity Section, whose chief at the time was Jack Smith.
The undercover operation that followed was named FRESHMAN FIFTEEN. Its interim authority listed three objectives, the first being to gather enough evidence “to indict and arrest Swalwell and Fang.” It said financial records showed Fang had arranged conduit contributions to the campaign at least twice in 2013 and twice more in 2014, and that she told someone she could arrange a meeting with Swalwell for a $5,000 contribution. An internship, she said, would cost more.
The bureau went further than watching.
In March 2015, it asked for approval for a confidential source to give Swalwell’s campaign $1,000, and a federal prosecutor and Public Integrity attorney Richard Pilger concurred. The memo says the money was meant to help the source “ingratiate” themselves with Fang, and states that the investigation had paid no bribes to Swalwell or any other official. Agents searched a residence on April 27 and 28, 2015, logging business cards, U.S. Conference of Mayors documents and a name badge from a U.S.-Asia Institute event bearing Fang’s and Swalwell’s names.
Two days later, on April 30, 2015, senior FBI officials gave Swalwell a classified briefing at the Capitol on how foreign governments target politicians, and on Fang’s connections to Chinese intelligence. He wasn’t asked questions. The notes record that he volunteered that he saw her about every two months, that she had been in his campaign office, and that she had never asked what his office was working on. He asked the agents what laws she might be breaking.
Agents interviewed him on March 4, 2016. He told them he had cut off contact with Fang after he first met with the FBI, and he was told the substance of the interview would go to a grand jury in the Northern District of California. On Feb. 8, 2017, the FBI retitled the case. “Investigation to date has not found violations of federal corruption statutes perpetrated by Congressman Eric Swalwell,” the memo says. Pilger concurred, and Swalwell’s name came off the file.
The charges nobody filed
The closing memo, dated May 2, 2017, is the shortest document in the file and the most consequential. It found no evidence of a quid pro quo between Fang and the congressman or his office. It did find evidence that she had broken several laws. The list includes making contributions in another person’s name and from a foreign national, falsifying records, false statements, international bulk cash smuggling, and acting as an unregistered agent of a foreign government.
She was never charged with any of them.
Fang had left the United States and been barred from re-entry, the memo says. After consulting the U.S. Attorney’s Office, the head of the San Francisco office decided that prosecution was “non-viable due to national security reasons.” The memo doesn’t say what those reasons were. The next day, an agent handed the items seized in the 2015 search to a lawyer at a San Francisco law firm.

What the release leaves out
Large parts of both packets are blacked out, including the names of agents, sources and other people interviewed, and several pages of a sealed court application and order. The file doesn’t show what intelligence placed Fang’s parents in the MSS, or what the “national security reasons” were. Some of the interview notes record second-hand gossip that the FBI wrote down without confirming. We have left those out.
Swalwell, who left Congress before the release, has denied wrongdoing and was never charged. The House Ethics Committee closed its own review in 2023 without finding a violation, Pleasanton Weekly reported. The records were declassified by the White House rather than released through the FBI’s FOIA process, and the task force didn’t say why it chose this file.
