San Francisco Mayor Gavin Newsom swore in openly gay attorney David Campos to replace Tom Ammiano on the San Francisco Board of Supervisors. Ammiano won his election to the California State Assembly on Nov. 4, carrying a Victory Fund endorsement.

Campos, who will represent the city’s ninth district, came to the United States at the age of 14 as an undocumented immigrant from Guatemala. He became an American citizen in 1997, according to the San Francisco Chronicle.

The paper reports:

“I might be the first undocumented person elected to the Board of Supervisors,” Campos said to cheers. “I think it’s only fitting in this very difficult time to be an immigrant that something like this would happen in San Francisco. It says a lot about the city.”

Campos, who will represent the largely Latino Mission District as well as Bernal Heights, also pledged, in Spanish, to continue working for the rights of Latinos and immigrants.

He will be joined by Supervisors-elect Eric Mar, David Chiu and John Avalos when the entire new board is sworn in Jan. 8.
