Winfrey last fully endorsed and campaigned for a candidate was September 25, 2006 when she endorsed then-Senator Barack Obama for President of the United States.
"I am honored to have Oprah join me for uplifting and honest conversations with voters about the clear choice before us in this election and the boundless potential of Georgians", reads a statement from Abrams to BuzzFeed News.
Winfrey is the latest high-profile Hollywood figure to go all-in for Abrams, whose candidacy has risen to national prominence as the former state legislator and Yale Law School graduate became the first African American woman to become a major party nominee for USA governor, and is vying to be Georgia's first black governor.
Winfrey isn't the only celebrity knocking on doors in support of Abrams.
Normally, celebrity support to boost a Democrat's chances in a typically red state would elicit a few chuckles from those who know exactly how far star power actually goes outside deep-blue liberal strongholds. Abrams appeared with Common and explained that Georgia's Gubernatorial race had national implications on the optics of political leadership in America. She has the support of 84 percent of black voters, and 74 percent of Atlanta metro voters, who traditionally vote Democratic. Obama's appearance is part of a string of nationwide stops to support Democrats in tightly contested races.
Kemp reportedly suggested rescheduling the debate to Monday night, but Abrams said she had already made plans to meet with voters in southeastern Georgia at that time.
Abrams hopes to make history on Election Day by becoming the first African-American female elected governor in US history.
