The Trump campaign team is filing a lawsuit to stop vote counting in Georgia, a campaign official said.

It is unclear whether the suit will be successful.

"President Trump and his team are fighting for the good of the nation to uphold the rule of law, and Georgia’s law is very clear: to legally count, mail ballots must be received by 7:00 p.m. on Election Day.

"That’s still the law, even after Democrats sued earlier this year to extend the deadline and delay Election Day—President Trump and Republicans fought to uphold Georgia law, and we won," Trump Deputy Campaign Manager Justin Clark said in a statement.

Mr. Clark went on to say that "a Republican poll observer in Georgia witnessed 53 late absentee ballots illegally added to a stack of on-time absentee ballots in Chatham County.

"We will not allow Democrat election officials to steal this election from President Trump with late, illegal ballots. President Trump and the Georgia Republican Party have filed suit to require all Georgia counties to separate any and all late-arriving ballots from all legally cast ballots to ensure a free, fair election in which only legal, valid ballots count." 

Separately, David Shafer, the chairman of the Georgia state GOP, tweeted a short time ago, "I have authorized lawyers for the Georgia Republican Party to file an emergency petition against the Chatham County Board of Elections to enforce election laws and prevent the unlawful counting of absentee ballots received after the election."

Trump advisers are nervously watching the final returns in Georgia, and have been taken aback by Biden's performance in what was thought to be a GOP stronghold. 

Both Trump advisers said African American turnout in Georgia for Biden is exceeding their expectations, resulting in a very tight race. 

Still, both advisers believe Trump has a better chance of closing the gap in Arizona than Biden has in Georgia.
