Possible 2020 Democratic contender Sen. Elizabeth Warren threw cold-water on the presidential buzz surrounding television superstar Oprah Winfrey on Wednesday, telling CNN she “doesn’t know” if the US is prepared for another billionaire president.

The liberal lawmaker was speaking with CNN’s Alisyn Camerota when she was asked to comment on Winfrey’s highly-publicized acceptance speech at the 75th annual Golden Globe Awards over the weekend, where the TV star pledged to the American people that “a new day is on the horizon.”

“Senator Warren, last question. Oprah Winfrey for president, your thoughts?” asked the ‘New Day’ host.

“You know, wasn’t that a fabulous speech?” deflected Warren. “And hearing Oprah’s voice and her energy and passion and her determination, it’s inspiring to all of us, and she shows great leadership. And I am delighted that she’s doing it.”

“Is the country hungry for another mega-celebrity billionaire?” pressed Camerota.

“I don’t know. But here’s what I do know. We are, right now, in the middle of a fight that will determine our future for generations to come,” said the Senator from Massachusetts.
