"I absolutely don't think her position has changed, I don't", King said of Winfrey, who has previously denied a desire to run for office.
The message was to all, however Oprah said to the young girls watching: "A new day is on the horizon".
"I like Oprah. I don't think she's going to run", Trump said.
Winfrey had sparked off speculation that she could run for president in 2020 with her epic Golden Globes speech on Sunday, January 7, 2018.
But it was her exhortation of the legions of women who have called out sexual harassers - and her dream of a day "when nobody has to say "me too" again" - that got some influential political operatives thinking Winfrey might be just what the Democrats need.

In fact, Winfrey told Bloomberg last March that Trump's election inspired her to consider the possibility.
The 64-year-old media mogul has become a cultural phenomenon over the past 30-plus years, born into a poor home in MS but breaking through as a television news and talk show personality in the 1980s. "I'd love to have Oprah". "4 years ago she strongly supported Obama-now she is silent". Oprah would always be my first choice. "I think we'd win easily, actually", Trump told ABC News at the time.
Some political operatives think she has what it takes to be a viable presidential contender. Ivanka caught a lot of flak on Twitter for her vague sentiment of solidarity with women while she continues to serve in the administration of her father, who has multiple accusations of sexual harrassment against him and spoke on audio tape about groping women without their consent.
