They're one of the old money families in SF - the Aliotos. His grandfather was the ex-Mayor from 1968-1976. Allegedly had mob ties as well, but NorCal ain't the Eastern Seaboard so ymmv.

Around 4 members of that family have been on the SF Board of Supervisors as well and they have a LOT of property holdings around Union Square.

They're also good family friends with Newsom (he appointed the assaulted SFFD's aunt to be a Supervisor when he was elected mayor and had to vacate his Supervisor seat) and Willie Brown (London Breed and Kamala Harris's mentor. Also a former mayor of SF responsible for the redevelopment of Hayes Valley, Mission Bay, and Van Ness. They have beef with Harris though because she endorses Breed).

They own one of the major regional law firms here (Alioto Law), were in the SF Giant's board, and also own a bunch of the property around Fisherman's Wharf (the now shuttered Italian restaurant Alioto's) and one of the major Car repair companies here (Alioto's Garage).

Edit: wasn't Joe Alioto that's in the ICU, but a family friend of theirs, but the Alioto family has taken up the cause now (bit of political intrigue too btw because of local elections)
