From CBS News' Maria Gavrilovic:
(DENVER) Oprah Winfrey, arguably Barack Obama's most famous supporter, was on hand last night to celebrate her friend's big night. Watching the speech from a sky box at Invesco Field, Winfrey was seen hugging friends and smiling during the acceptance speech. "I've never experienced anything like that," she later said, "I think it was anything anyone could ever expect."
Winfrey said she "googled" the Martin Luther King, "I Have A Dream" speech yesterday morning, and re-read portions of it. "He talks about the promise of democracy," she said, "And I think today that promise was fulfilled in a way that I never imagined."
Winfrey was visibly moved by Obama's speech, calling it "transcendent" and "transformational," but she expressed concern that voters may not feel the same. "I only pray in the deepest part of my being that America will rise to this moment."
She added that Obama's presidential race and quick rise in the Democratic Party is "the most powerful thing I've ever experienced."
Despite being the "Queen of Talk," Winfrey had to wrap her short conversation with reporters because the Secret Service threatened to lock in her motorcade if she did not leave.
