Before exiting Invesco Field Thursday night, Oprah Winfrey stopped and answered a few questions from reporters.
She said the night was extraordinary and explained, "I have never experienced anything like that."
She said she had re-read Martin Luther King, Jr.'s "I Have A Dream" speech in the morning and referencing King's line about making real "the promise of democracy," she said that tonight "that promise was fulfilled."
Before leaving with an entourage that included Gayle King and Oscar-winner Forest Whitaker, she said she hoped Americans would "rise to the moment" and support Obama.
