If Abrams wins next week, the former Georgia state House minority leader would become the country's first female African-American governor.
Mr Pence has criticised Ms Abrams for using Ms Winfrey during her campaign. I don't wanna go in those waters, ' she said, shaking her head and waving her finger.
She praised Abrams as a leader who "will serve the underserved of the state of Georgia". "We have more voters who participate in run-offs than she does", the source says. She faces Republican Brian Kemp, who was appearing with Vice President Mike Pence at a trio of events in the state Thursday.
Winfrey pointed out that she's an Independent, and she votes for her "values".
She added that Abrams is "standing strong for the values that matter to me and the values that matter to Georgians all over this state".
The hotly contested Georgia governor's race has garnered national attention and is now neck and neck.
Winfrey did not mention Pence who, in appearances same day, charged Abrams with being "bankrolled by Hollywood liberals" and derided Winfrey's presence as well as a recent campaign appearance for Abrams by Will Ferrell.
In the past two years, his most memorable moment was that time he spent a quarter million in taxpayer money flying to a football game just so he could pointedly walk out in protest. "Rather it lives and thrives in making sure that everybody is lifted by the community", Winfrey said.
