Former White House chief strategist Stephen Bannon reportedly worried about Oprah Winfrey campaigning for Democrats in the 2018 midterm elections, saying she could be an "existential threat" to the Trump presidency.

According to an updated version of "Devil's Bargain" by Josh Green, Bannon believes Democrats would attempt to impeach President Trump Donald John TrumpObama calls on Senate not to fill Ginsburg's vacancy until after election Planned Parenthood: 'The fate of our rights' depends on Ginsburg replacement Progressive group to spend M in ad campaign on Supreme Court vacancy MORE if they take control of the House, Politico reported.

"The anti-patriarchy movement is going to undo ten thousand years of recorded history," Bannon said, according to the book.

"You watch. The time has come. Women are gonna take charge of society. And they couldn’t juxtapose a better villain than Trump. He is the patriarch. This" — the Golden Globe Awards — "is a definitional moment in the culture. It’ll never be the same going forward.”

Winfrey's speech during the Golden Globe Awards, addressing the "Me Too" and "Times Up" movements, spurred talk of a potential White House run in 2020.

“For too long, women have not been heard or believed if they dared to speak their truth to the power of those men,” Winfrey said while accepting the Cecil B. DeMille Award at the ceremony. “But their time is up. Their time is up!”

Winfrey said last month she doesn't think she has the "DNA" for a White House run.

"I’ve always felt very secure and confident with myself in knowing what I could do and what I could not. And so it’s not something that interests me. I don’t have the DNA for it," Winfrey said in an interview last month.

Trump last month told reporters he didn't think Winfrey would launch a presidential bid, but noted he believed he would beat her.

"Yeah, I'll beat Oprah. Oprah will be lots of fun,” the president said. “I don’t think she’s going to run.”
