Here is a photo of Kamala Harris (29) kissing Willie Brown (60), appearing in the San Luis Obispo Telegram Tribune, dated November 8, 1995. At the time Brown was running for mayor of SF. My source is a Gateway Pundit article.
The Gateway Pundit article has video of an ABC News profile of Brown which talks about his "fine women" and "fast cars" while showing him with Harris and a Porsche and also reports this.
“Excuse me, are you his daughter?” a woman asks Kamala Harris.
Harris looks stunned: “No, I’m not.”
