SAN FRANCISCO (KRON) — Another name has been added to the San Francisco mayoral race. A KRON4 source confirmed Thursday that city supervisor Aaron Peskin is running for mayor.

Sources say his decision is based in part on former San Francisco supervisor Mark Farrell’s decision to run and the fact that there was no progressive candidate in the race. He will officially enter the race next week.

Peskin joins incumbent mayor London Breed, supervisor Asha Safai, philanthropist Daniel Lurie and Farrell in the race.

Peskin is the current president of the San Francisco Board of Supervisors. His District 3 includes North Beach, Chinatown and Union Square. He is set to term out this year.

His work as supervisor includes preserving and expanding affordable housing in San Francisco, according to his page on the board of supervisors’ website.

In 2021, he went into rehab for alcohol treatment. He issued a public apology at the time for “the tenor that I have struck in my public relationships.”
