An attorney representing the woman Donald Sterling was talking to when he made racist remarks said Thursday that the hour-long conversation was taped by mutual agreement last September and provided to a friend for safekeeping, who then leaked it to TMZ. V. Stiviano sent two snippets of the conversation, recorded in her Los Angeles duplex, to a friend who released them without her permission, lawyer Siamak Nehoray said. He would not identify the friend.
