(CNN) Democratic candidate Stacey Abrams is refusing to accept Republican rival Brian Kemp's declaration of victory in the Georgia gubernatorial race and is considering legal action in the high-profile contest.

"Our opponent has had his office declare himself the victor and we do not accept that," the Abrams campaign said in a phone call with reporters Wednesday evening.

CNN has not projected a winner in the race. Kemp, Georgia's secretary of state, is currently ahead of Abrams by nearly 63,000 votes with 99% of precincts reporting, according to CNN election results . He has 50.3% of the vote, Abrams has 48.7% and Libertarian candidate Ted Metz has 0.9%. If no candidate receives 50%, there will be a runoff in early December.

"Based on counts released by the Secretary of State's office, Brian Kemp's margin is so large that the number of provisional ballots and overseas ballots will not change his Election Day victory," Cody Hall, the Kemp campaign's press secretary, had said in a statement earlier Wednesday. "Simply put, it is mathematically impossible for Stacey Abrams to win or force a run-off election."
