Los Angeles Mayor Antonio Villaraigosa is expected to announce his endorsement Friday in the California attorney general race, and it's not going to be former L.A. city attorney and fellow Democrat Rocky Delgadillo.

Villaraigosa will throw his support to Democratic candidate Kamala D. Harris, the San Francisco district attorney. The nod is scheduled to become official at high noon on the steps of Los Angeles City Hall.

Villaraigosa and Harris share the same political strategist, Ace Smith of San Francisco.

Assemblymen Ted Lieu of Torrance, Alberto Torrico of Newark and Pedro Nava of Santa Barbara also are in the race for the Democratic nomination, as is Chris Kelly, Facebook's chief privacy officer.

Los Angeles Dist. Atty. Steve Cooley, a Republican elected three times in Democratic-leaning Los Angeles County, is running for the GOP nomination, as are state Sen. Tom Harman of Huntington Beach and John Eastman, former dean of Chapman University Law School.
