unty Registrar of Voters, declined to comment, saying the office was  still investigating  the matter.

Shapiro was among 28 people charged Monday in a federal sweep targeting alleged illegal voting, voter registration and related offenses in California. All 28 are lawful permanent residents, according to the Justice Department.

Another defendant, Manakotau Mataele Finau, a Tongan national who lives in Hayward, according to charging documents, could not be reached for comment Monday. The documents say Finau became a lawful permanent resident of the United States in 1969.

Prosecutors allege Finau registered electronically on Nov. 3, 2024, signed another registration form the following day and voted in the Nov. 5 general election. Both registration forms included declarations of U.S. citizenship, according to the charging documents, which did not identify the evidence supporting the voting allegation.

Prosecutors also allege Finau falsely denied previously claiming U.S. citizenship or voting in a U.S. election when applying for naturalization in July 2026.

The charges are part of the Trump administration's broader effort to target noncitizen voting ahead of the November midterms. Trump has repeatedly claimed such voting is widespread, although studies have found it is rare.

The Justice Department sued California last week, seeking to block the counting of mail ballots from more than 20,000 registered voters federal officials say are likely noncitizens until their citizenship can be verified. California's secretary of state has disputed the adequacy of the information and methodology supporting the list.
