The mayor of a Los Angeles suburb resigned Monday, as U.S. officials announced that she will plead guilty in federal court to acting as an illegal agent for the Chinese government.

Federal prosecutors announced Monday that Eileen Wang, 58, of Arcadia, Calif., has been charged with one count of acting in the U.S. as an illegal agent of a foreign government and is “expected to plead guilty in the coming weeks.” The charge is punishable with up to 10 years in prison.

“Mayor Wang admitted to acting as a foreign agent from at least 2020 through 2022 - promoting PRC propaganda in the U.S. and acting at PRC’s direction to promote their interests,” FBI Director Kash Patel posted on X. “FBI and our federal partners continue to move aggressively to root out this kind of influence in American institutions all over the country.”

Wang was elected in November 2022 to the five-member Arcadia City Council, where the mayor is selected on a rotating basis. City Manager Dominic Lazzaretto said in a statement Monday that Wang, who became mayor in February, has resigned from the council.
