In a recording released by TMZ two weeks ago, Sterling tells a female friend,
"Did you apologize to him?" Cooper asked, according to a CNN transcript.
"If I said anything wrong, I'm sorry," Sterling responded. "He's a good person. I mean, what am I going to say? Has he done everything he can do to help minorities? I don't think so. But I'll say it, he's great. But I don't think he's a good example for the children of Los Angeles."
Sterling apologized for what he said on the tape.
"When I listen to that tape, I don't even know how I can say words like that.... I don't know why the girl had me say those things," he said. "I was baited ... I mean, that's not the way I talk. I don't talk about people for one thing, ever. I talk about ideas and other things. I don't talk about people."
At the time the tape was released, Stiviano and Sterling's wife, Shelly, were locked in a legal battle, with Shelly demanding that Stiviano give back cars and a $1.8-million condo that Donald Sterling had allegedly given her.
Sterling on Sunday also apologized for his comments.
"I'm a good member who made a mistake and I'm apologizing and I'm asking for forgiveness," he said on CNN. "Am I entitled to one mistake, am I after 35 years? I mean, I love my league, I love my partners. Am I entitled to one mistake? It's a terrible mistake, and I'll never do it again."
He added: "I'm not a racist. I made a terrible mistake."
