Anyone who’s watched at least one episode from Oprah Winfrey’s SuperSoul Sundays series can easily discern the mogul isn’t one to entertain foolishness.

So when President Donald Trump angry-tweeted Winfrey was “very insecure” for hosting a bipartisan discussion about the president on a 60 Minutes segment, Winfrey didn’t get riled up. She just double-checked to make sure she did her job right.

“I woke up and I just thought,” Oprah said while shrugging her shoulders on Thursday’s episode of The Ellen DeGeneres Show. “And I don’t like giving negativity power, so I just thought, what?”

“What I actually really did was I went back and looked at the tape to see if there was any place that that could be true,” Winfrey continued. “Did I feel like …  it was slanted or biased.”

She said she reviewed the taping before it aired to ensure she wasn’t being partial.

“The first time I saw it, I said there’s something missing here from the conversation,” Winfrey said. “When I had asked the question of, ‘Do you think, do you care about what other people think about America?’ And they only used the Democratic side. And I said, I remembered the guy Matt had said, ‘No, we’re the only people that are worried what other countries are thinking of us.’ And I said, ‘I think you should go back and put that in because it makes it more balanced.’ So, I was working very hard to do the opposite of what I was hate-tweeted about, so, it’s okay.”

Winfrey shared that there are even seven other producers who serve as bias detectors and conclude whether programming is equitable.

“I called the producers. Because what actually happened was when you do 60 Minutes, you sit in a room with at least seven other people who critique the piece before you air it, before you do the introduction to it, and then they give you the critique,” she said. “So, they critique every word and is this fair—you have this whole panel of people looking at whether it was fair.”

The billionaire did her job right. And that’s all she cares about.
