The media mogul will campaign on Thursday, Nov. 1, with the Democratic Abrams by knocking on doors and holding two town hall meetings in Cobb County and DeKalb County -- areas that traditionally vote Republican.
Abrams’ show of support for illegal immigration and turning Georgia into a Sanctuary state did not resonate with voters.
Former president Obama will hold a rally for Abrams at Forbes Arena on Morehouse College campus in Atlanta on Friday, Nov. 2 at 5 p.m..

In a statement to BuzzFeed News, Abrams said: "I am honored to have Oprah join me for uplifting and honest conversations with voters about the clear choice before us in this election."
Abrams previously accused her opponent Kemp of using his position as secretary of state to gain an unfair advantage over her.
Kemp reportedly purged the voter rolls of 300,000 registered voters whose voter registration forms contained errors.
Last week, a federal judge ruled that elections officials must contact voters and offer them the chance to correct their forms.
Other Democrats who have campaigned in Georgia for Abrams are New Jersey Sen. Cory Booker, former vice president Joe Biden and Sen. Elizabeth Warren.
