ARCADIA — Eileen Wang pleaded guilty on May 29, 2026, to acting as an unregistered agent of the Chinese government, a felony charge that led to her resignation as mayor of Arcadia and as a City Council member. Her guilty plea followed the unsealing of federal charges on May 11, 2026, which prompted her immediate departure from both roles.

Wang admitted in federal court that between 2020 and 2022—before she was sworn into office in December 2022—she operated a website called 'U.S. News Center' with her then-fiancé Yaoning 'Mike' Sun, publishing pro-Beijing content directed by Chinese government officials. She posted pre-written articles supplied by those officials without disclosing their origin, made edits at their request, and shared website viewership metrics with them.

First Assistant U.S. Attorney Bill Essayli said: 'Individuals in our country who covertly do the bidding of foreign governments undermine our democracy.' Essayli added: 'This plea agreement is the latest success in our determination to defend the homeland against China’s efforts to corrupt our institutions.' Assistant Director Roman Rozhavsky of the FBI’s Counterintelligence and Espionage Division said: 'By her own admission, Eileen Wang secretly served the interests of the Chinese government.' Rozhavsky also said: 'Let this serve as a clear warning: individuals who act on behalf of foreign governments to influence our democracy will be identified, investigated, and brought to justice.'

A statement from Wang’s lawyers said: 'She apologizes and is sorry for the mistakes she has made in her personal life. Her love and devotion for the Arcadia community have not changed and did not waver.' Wang has suggested she was misled by Sun, who pleaded guilty to the same charge and is serving a four-year prison sentence.

The city of Arcadia stated that the investigation concerns individual conduct that ceased after Wang took office and emphasized that no city finances or staff were involved. Wang faces a statutory maximum of 10 years in federal prison, with sentencing scheduled for October 6, 2026.
