Federal authorities have filed a civil complaint seeking to revoke the U.S. citizenship of former North Miami Mayor Philippe Bien-Aime, accusing him of lying about his identity and immigration history to obtain naturalization.

In a 13-page complaint filed by the Department of Justice, the government alleges Bien-Aime “willfully misrepresented his identity and immigration history throughout the naturalization process,” according to documents reviewed by NBC6.

President Donald Trump criticized Pima County Sheriff Chris Nanos, who has played a lead role in the investigation in the disappearance of Nancy Guthrie, for sharing information on the FBI’s investigation and use of technology.

The case, which began on February 1, 2026, when Nancy Guthrie went missing from her home in the Catalina Foothills area near Tucson, Arizona, has involved local law enforcement, the FBI, and has generated significant public attention. President Trump has repeatedly commented on the case and stated that all federal resources are available for the ongoing search.
