Newly declassified FBI records made public this week have reignited one of Washington’s longest-running espionage scandals, putting fresh, uncomfortable detail around a name that first surfaced back in 2020: Fang Fang.
The files, released Monday, August 17, 2026, by the White House Government Transparency Task Force, lay out a years-long FBI investigation into how the woman also known as Christine Fang allegedly built a network inside Bay Area and national Democratic politics, and how one of her closest relationships was with then-Congressman Eric Swalwell of California. The documents describe a sexual relationship, campaign donations routed through third parties, foreign interns placed inside a sitting congressman’s office, and a parallel effort by the bureau to flip Fang and turn her into an informant.
Here’s everything currently known about who Fang Fang is, what the declassified files actually say, and where the Swalwell connection stands today.
Who Is Fang Fang (Christine Fang)?
Fang Fang is the alias used by Christine Fang, a Chinese national who moved to the United States around 2011 to study at California State University, East Bay in Hayward. Over the following four years, U.S. counterintelligence officials say she cultivated relationships with rising American politicians using fundraising, networking, and personal relationships, allegedly on behalf of China’s Ministry of State Security, Beijing’s civilian intelligence agency.
She was first named publicly in a landmark December 2020 investigation by Axios, which reported that Fang had socialized with, fundraised for, and in some cases grown personally close to a number of local and national Democratic figures, including Swalwell, Congresswoman Tulsi Gabbard, and Congressman Ro Khanna. Reporting at the time also alleged sexual relationships with at least two Midwestern mayors as part of what was described as a broader, years-long intelligence-gathering campaign.
Fang left the United States abruptly in mid-2015 while under FBI investigation and has not returned since. She has never been publicly charged with a crime, largely because she was already back in China by the time investigators built their case.
What the Declassified FBI Files Reveal
The new document release includes two major sets of records. The first is described as a 97-page collection of memoranda, interview summaries, and investigative material tied to a formal public-corruption probe into Swalwell’s campaign, reportedly codenamed “Freshman Fifteen.” The second is a separate 50-page chronological file covering the bureau’s earlier direct contact with Fang, before the corruption investigation ever opened.
The Swalwell Relationship, According to the FBI
According to the records, Swalwell cooperated with investigators and sat for multiple FBI interviews, during which he acknowledged a personal relationship with Fang and confirmed that she had referred interns into both his campaign and his congressional office. Coverage of the files indicates the encounters described took place before Swalwell was elected to Congress, during the 2012 election cycle, and that Fang visited his apartment on at least two occasions.
Investigators also examined how Swalwell’s early campaign finances were structured. The bureau reportedly found that his campaign received over $1.1 million in individual contributions between January 2013 and December 2014, and agents worked to trace whether any of that money had been funneled through American intermediaries to conceal Fang as the true, prohibited foreign source. One version of events described to investigators involved a winery owner who said Fang had told him to simply bring his checkbook, with an understanding that she would reimburse the contribution herself.
Despite the scope of the inquiry, the files also contain a detail that cuts against the more sensational headlines: the FBI ultimately concluded it had not found a federal statutory violation attributable to Swalwell personally, and on February 8, 2017, it formally reclassified the case, removing him as a subject and narrowing the investigation to Fang’s alleged conduct alone.
“Rusty Thumbs”: The FBI’s Attempt to Recruit Fang
One of the more striking threads in the newly released material is that the bureau tried to recruit Fang as a confidential informant before the corruption case against her ever began. Agents assigned her the code name “Rusty Thumbs,” built a fictitious company, and used an undercover employee to develop a working relationship with her, reportedly starting with a meeting in Las Vegas in May 2013. Fang went on to sign a contractor agreement with the undercover operation in June 2013, apparently unaware that the FBI, rather than a genuine business partner, was on the other side of the arrangement.
What Happened to the Case Against Fang
The files reportedly catalogue a long list of potential violations investigators believed Fang had committed, including illegal campaign contributions made in another person’s name, contributions from a foreign national, falsified records, a false-statement scheme, bulk cash smuggling, and acting as an unregistered foreign agent. Even so, the Department of Justice’s Public Integrity Section, headed at the time by prosecutor Jack Smith, declined to bring charges. The declassified documents reportedly do not spell out why prosecutors passed on the case, and by the time any decision was made, Fang had already left the country.
Eric Swalwell’s Response
Swalwell’s office has maintained for years that he cooperated fully with the FBI’s investigation once he was alerted to Fang’s suspected ties to Chinese intelligence, and that he cut off contact with her as soon as he learned about the concerns. In comments cited around the earlier 2020 Axios report, his office noted that he had provided information about Fang to the bureau and, because some of what he knew involved potentially classified matters, was limited in what he could say publicly. That basic position has not changed following this week’s release, even as the documents themselves added far more specific and personal detail than had previously been confirmed.
It’s worth noting that Swalwell is no longer in Congress. He left his House seat earlier in 2026 following a separate, unrelated controversy involving allegations from members of his staff, an episode he addressed publicly with an apology to his family for what he called past errors in judgment.
Why This Story Is Back in the News Now
The renewed attention traces back to a broader push by the current administration to declassify material tied to alleged foreign interference in American politics. President Trump ordered the Fang-Swalwell files released, and the White House Government Transparency Task Force made them public as part of that wider transparency effort. Investigative outlets including Just the News and independent reporter Sam Cooper were among the first to review and detail the contents.
For a story that has simmered in the background of American politics since 2020, the declassified files represent the most detailed official account yet of what the FBI actually found, and how close it came to pursuing charges against a sitting member of Congress before ultimately pulling back.
Fang Fang, or Christine Fang, remains a Chinese national accused of running a years-long political influence operation in California before disappearing back to China in 2015 amid an active FBI probe. The newly declassified files confirm, in the bureau’s own words, that she had a personal relationship with Eric Swalwell, placed interns close to his office, and is suspected of funneling illegal donations into his campaign, all while the FBI was simultaneously trying to recruit her as a source on Chinese influence operations. Swalwell was investigated but ultimately not charged, and Fang was never prosecuted after leaving the United States. Whether further documents, testimony, or congressional action follow this release remains to be seen.
