Abrams said that she planned to start an organisation to fight for more equitable voting laws and would soon bring "a major federal lawsuit against the state of Georgia for gross mismanagement of this election".
At a news conference, Georgia Democrats cast doubt on the legitimacy of any election count that ends with the former secretary of state being certified as the victor of a fiercely fought election against Stacey Abrams, who's seeking to become the first black woman elected governor in the US.
Georgia authorities say a senator arrested at a state Capitol demonstration over uncounted election ballots was charged with obstruction because she helped create "a human wall" that hindered police.
Kemp now leads Abrams by almost 59,000 votes, but more than 20 counties across the state have yet to certify their election results, and thousands of provisional and absentee ballots remain uncounted.
Invoking a statute that has never before been used in a major election in the state, Abrams' team is collecting evidence from across the state that her Republican opponent, Brian Kemp, was behind "misconduct, fraud, or irregularities.sufficient to change or place in doubt the results".
Aides close to Abrams said that since the election she had been wrestling with competing priorities: She wanted to advance her assertions that Georgia's elections process makes it too hard for some citizens to vote.
Stacey Abrams had hoped to become the nation's first elected female African-American governor.
Trump says he answered Mueller questions, not his lawyers
Trump said his lawyers will review the answers before they're sent to Mueller. "I imagine it's ending now", he said. Trump on Friday again criticized the probe as a "witch hunt" and said there was no such collusion.

Trump considers ousting top aide who feuded with Melania
She said she gave the president "my honest advice and honest opinions and then he does what he wants to do". Trump reportedly clashed over aspects of the first lady's trip to Africa last month.
Earlier Friday, Abrams was considering filing a separate lawsuit contesting the results and demanding a new election. His campaign aides spent much of this week attacking Democratic efforts in court, while Abrams picked up a series of important, if not ultimately pivotal, legal victories.
Abrams, meanwhile, sent volunteers across the state in search of voters whose ballots were rejected.
Clinton closed her speech with a snide remark about the size of Donald Trump's inauguration crowd - a fitting end to a speech about not being able to accept the results of a full and fair election with dignity. The apparent governor-elect's campaign had been harshly critical of Abrams for not conceding the race earlier, calling her desperate.
Kemp's lead had dwindled since Election Day as absentee and provisional ballots trickled in.
"The election is over and hardworking Georgians are ready to move forward", he said.
Both cases named Kemp-who was secretary of state until last Thursday-as a defendant, and both sought court orders involving thousands of rejected absentee ballots in Georgia's 159 counties. "We can no longer dwell on the divisive politics of the past but must focus on Georgia's bright and promising future".
The Abrams for Governor campaign released an ad today on their contention that voters faced lots of problems at the polls and encouraging them to report their stories. But she also recognized that a protracted legal fight would harm that cause and potentially her political future. Another judge ordered the state's election officials to preserve and count all provisional ballots. "But stoicism is a luxury, and silence is a weapon for those who would quiet the voices of the people", she said. The next big shot for Democrats is a 2020 Senate race, with Republican Sen.
