FBI: CAUGHT — Politician Was Secret Chinese Agent — Worked Inside U.S. City Hall

The Silent Orchestrator: The Hidden Life of Yaoning Mike Sun

The Resume of a Covert Agent

In February 2023, a 63-year-old man named Yaoning Mike Sun sat in his home in Chino Hills, California, and composed a report. To his neighbors, he was a pillar of the community—a man involved in local politics and Chinese American cultural circles. But the document he was writing was not intended for any American eyes. It was a professional pitch addressed to the officials of the People’s Republic of China (PRC). This report acted as a resume of covert services rendered on American soil. Sun detailed his history as a former soldier in the People’s Liberation Army (PLA) and listed his accomplishments: leading delegations, suppressing “hostile forces,” and surveilling groups that Beijing deemed threats. Most chillingly, he boasted about his work during the 2022 midterm elections, claiming he had “orchestrated” a team to win a city council seat for a “new political star.” This report was a request for more funding—specifically $80,000 to stage a pro-China demonstration at a Fourth of July parade in the heart of Washington, D.C.

The PLA Veteran in the Suburbs

Yaoning Sun’s journey did not begin in California; it began in the ranks of the Chinese military. In his own communications with PRC officials, he cited his past service in the PLA as a primary credential, proving his loyalty and capability to execute directives inside the United States. After moving to Southern California, he reinvented himself as a civic leader. He built a network of relationships with elected officials and campaign organizers, positioning himself as a vital bridge between the local Chinese American community and the American political system. This reinvention was his greatest asset, allowing him to operate as a covert agent of the Chinese government without ever notifying the U.S. Attorney General, as required by the Foreign Agents Registration Act (FARA).

The Intelligence Node: John Chen and the Xi Connection

Sun did not operate in a vacuum. Federal prosecutors identified his primary handler as John Chen (also known as Chen Jun), a high-level figure within the PRC intelligence apparatus. Chen was a man of significant status, someone who attended elite Communist Party functions and had personally met with President Xi Jinping. While Chen managed the high-level strategy from the shadows of the Chinese intelligence network, Sun served as his “right-hand man” on the ground in California. Their partnership was a clean division of labor: Chen provided the taskings and the connection to the central government, while Sun executed the tactical operations, organized the teams, and delivered the results. Together, they spent decades building a structure of influence designed to manipulate American perceptions and policy from the local level upward.

The Propaganda Machine: The Fake News Website

One of the primary tools utilized by Sun and a local politician—identified by prosecutors only as “Individual One”—was a news website marketed to the Chinese American community in Southern California. On the surface, the site appeared to be a helpful resource for local news and cultural perspectives. In reality, it was a propaganda platform directly controlled by Beijing. Sun and his associate received specific directives from PRC officials regarding what content to post, ensuring that the information consumed by local residents aligned with the strategic interests of the Chinese Communist Party. This operation demonstrated how easily foreign influence can be disguised as “local journalism,” exploiting the trust of community members to disseminate state-sponsored narratives.

Orchestrating a City Council Election

The 2022 midterm election cycle marked a significant escalation in Sun’s activities. Acting as a campaign adviser for Individual One, Sun claimed in his reports that the entire campaign was an “orchestrated operation.” He didn’t view it as a democratic exercise, but as a tactical mission to place a “political star” into a position of authority. Individual One eventually won the election and took a seat on a Southern California city council. While the federal record does not establish whether Individual One knew of Sun’s covert ties to Chinese intelligence, the fact remains that a sitting American official reached office with the help of a man who was simultaneously reporting his success back to Beijing. This interference struck at the very heart of the American democratic process, turning a local election into a calculated transaction for foreign influence.

Real-Time Surveillance of a Head of State

In April 2023, the operational scope of Sun’s mission became even more aggressive. When the President of Taiwan, Tsai Ing-wen, visited Southern California, Sun was deployed as a covert surveillance asset. He did not attend the events as a spectator; he acted as an intelligence officer, tracking the President’s movements and sending real-time updates to a PRC consular official in Los Angeles. Sun photographed protesters on both sides—supporters of Taiwan and those opposing the visit—and transmitted these images to the Chinese government. This was a brazen act of espionage on American soil, where a foreign power received immediate intelligence on the movements of a democratic leader and the identities of American citizens exercising their First Amendment rights.

The Megaphone of Threats: John Chen’s Public Intimidation

While Sun worked the surveillance angle, his co-conspirator John Chen utilized public intimidation. During a pro-Taiwan protest in Los Angeles, Chen was captured on video using a megaphone to openly threaten the crowd. He told the protesters that if they held Chinese passports, they would be arrested upon their return to China because he was taking their photographs. For those with U.S. passports, he warned that they would be denied future Chinese visas. This wasn’t just political rhetoric; it was the direct application of transnational repression. The message was clear: the Chinese government was watching, even in the United States, and there would be consequences for those who opposed their agenda.

The Fall of the Operation

The FBI’s counterintelligence division had been tracking Sun and Chen’s activities for an extended period, utilizing physical surveillance and intelligence channels to build an airtight case. John Chen was the first to be taken into custody, arrested in the Southern District of New York. He eventually pleaded guilty to acting as an illegal agent of the PRC and conspiracy to bribe a public official, receiving a 20-month prison sentence in late 2024. Yaoning Mike Sun’s arrest followed, charging him with the specific count of acting as an unregistered agent of a foreign government. Sun chose to plead guilty in October 2025, facing the documented evidence of his reports to Beijing and his surveillance activities in Southern California.

Forty-Eight Months in Federal Prison

On February 9, 2026, Judge R. Gary Klausner sentenced Yaoning Mike Sun to 48 months (four years) in federal prison. During the sentencing, prosecutors emphasized the gravity of the breach: when Americans go to the polls, they deserve to know that those advising the candidates are not working for a foreign adversary. Sun’s four-year term was intended to reflect the seriousness of his “brazen violation of national sovereignty.” However, the sentence also highlights the difficulty of prosecuting influence operations that are designed to be legally deniable at every layer. While Sun is now behind bars, the city council seat he helped win remains occupied, and the full extent of the “orchestrated” election remains a secret from the voters who cast the ballots.

The $80,000 Fourth of July Request

Perhaps the most symbolic detail of Sun’s betrayal was his request for $80,000 to fund an operation on the Fourth of July in Washington, D.C. He wanted the Chinese government to pay for a pro-China demonstration during the very parade that celebrates American independence. This request, found in his February 2023 report, showcased his “institutional fluency” in executing Beijing’s taskings. He sought to use the most sacred American holiday as a backdrop for a display of foreign state influence. Whether the $80,000 was ever sent or the demonstration actually occurred remains unconfirmed in public filings, but the intent was clear: to undermine American sovereignty from within the heart of its capital.

The Ghost of “Individual One”

One of the most unsettling aspects of the Sun case is the unresolved status of “Individual One.” This politician, described by Sun as a “political star,” still holds office in a Southern California city. The federal government has not released the name of this individual, nor has the election been invalidated. The citizens of that city are currently represented by someone whose campaign was organized by a man taking orders from the People’s Republic of China. This leaves a lingering question about the integrity of local governance. If a covert agent can orchestrate an election and then disappear into the prison system without the candidate being named, the operation has, in some ways, achieved its goal of creating a lasting, invisible influence.

A Warning for American Democracy

The story of Yaoning Mike Sun is a stark reminder that modern espionage is not always about stealing military secrets or state codes. Often, it is about the patient, methodical manipulation of democratic institutions. By embedding himself in local politics, running propaganda through a fake news site, and surveilling domestic protests, Sun proved that the most effective foreign agents are those who look exactly like ordinary citizens. His case represents a new frontier in counterintelligence—one where the threat is wrapped in the texture of community engagement and civic participation. As the FBI’s Assistant Director for Counterintelligence noted, Sun’s actions were an attempt to undermine the very processes that define American life. The law reached Mike Sun, but the true challenge lies in identifying the many reports like his that are still being written by agents who haven’t been found yet.
