Lawrence-Hardy told the AP that Abrams will weigh legal considerations alongside her belief that many of her backers - particularly minority and poorer voters who don't regularly go to the polls - heeded her call to participate and ran into barriers. "Because concession means to acknowledge an act is right, true or proper", she said.
Top Abrams advisers outlined her prospective case to The Associated Press.
She railed against the election process and said there were mistakes that "clearly altered the outcome". "And I will not concede because the erosion of our democracy is not right". Republican Brian Kemp is expected to officially become the governor-elect after a long and contentious battle over provisional and absentee ballots. "Now, the courts are doing what Brian Kemp's Secretary of State office refused to - upholding and protecting Georgia's rights and underlining the need for free and fair elections in a state that has suffered from an acute assault on voting rights engineered by none other than Secretary of State Brian Kemp". Kemp said he was trying to maintain the integrity of Georgia's voter rolls.
The long-shot strategy, first reported by the Associated Press, comes as Georgia elections officials appear to be poised to certify Kemp as the victor in the hard-fought contest as early as Friday. She did not immediately return an email message seeking comment Friday.
Georgia's election earned a national spotlight this year when Abrams won an upset in the Democratic primary, becoming the first black woman to be a major party's nominee for governor.
The announcement followed more than a week of post-election legal maneuvering from her campaign and allies as they sought to find enough votes to reduce Kemp's lead and force a December 4 runoff. "Not would a hard-core partisan Democrat doubt a partisan Republican opponent", she said.
Trump says he has finished answering Mueller probe questions
Since then the two sides have reportedly jousted over whether the president had to answer and how he would do so - including the possibility that he would submit to a face-to-face interview with prosecutors.
The Associated Press earlier reported that Abrams' campaign chairwoman Allegra Lawrence-Hardy was working a team of almost three dozen lawyers who were drafting their petition against the results.
"We can no longer dwell on the divisive politics of the past but must focus on Georgia's bright and promising future", he said shortly after Ms Abrams' speech.
But as more counties completed their vote tallies, Abrams and her allies claimed there were thousands of outstanding ballots that never materialized.
His victory will keep the Georgia governor's mansion in GOP hands for a fifth consecutive term and demoralize Democrats who hoped to put the state on the presidential map in 2020. Trump bet big on Kemp, endorsing him ahead of Kemp's Republican primary runoff and campaigning for him the weekend prior to the November 6 election.
Democrat Stacey Abrams says she will file a federal lawsuit to challenge the "gross mismanagement" of Georgia elections.
The Abrams campaign had indicated it could pursue a drastic legal remedy on Friday, in which it would try to prove the election was fraudulent and essentially toss out the results for a new election.
