President-elect Joe Biden will travel to Georgia on Tuesday Dec. 15 to campaign for Democratic candidates Jon Ossoff and Rev. Raphael Warnock in their Senate runoff races, the Biden transition has announced.

Biden's visit will come during the first week of early voting in the Jan. 5  Senate runoff elections that could determine whether Democrats or Republicans control the U.S. Senate.

Pro-Trump attorney Sidney Powell has just lost her third straight case in her conspiracy-fueled bid to overturn the results of the 2020 presidential election, this time in Arizona.

As in the earlier cases, the judge did not look kindly on the unfounded claims that filled Powell's lawsuit. Judge Diane Humetewa, an Obama appointee, wrote in her dismissal Wednesday night that Powell's allegations might "find favor in the public sphere of gossip and innuendo," but they "cannot be substitute for earnest pleadings and procedure in federal court."

"They most certainly cannot be the basis for upending Arizona's 2020 General Election," Humetewa wrote.

Powell saw swift defeat in two cases Monday, with federal judges in Michigan and Georgia dismissing or denying her efforts there within hours of each other. Both of those rulings have since been appealed. Only Powell's Wisconsin case remains. A ruling is expected soon.

Less than 24 hours after the news broke that Biden would nominate Rep. Marcia Fudge, D-Ohio, to serve as his secretary of Housing and Urban Development, a high-profile figure within the progressive left appears poised to launch a bid for her House seat.

On Wednesday, candidacy paperwork bearing the name of former Ohio state Sen. Nina Turner was filed with the FEC for Fudge's 11th Congressional District seat. Sources close to Turner told ABC News to expect an announcement from Turner herself "soon."

While far from a national name, Turner is immensely popular within the Sen. Bernie Sanders-led progressive left after serving as a campaign surrogate and adviser during Sanders' 2016 and 2020 presidential campaigns. In between, she served as president of Our Revolution, the political action organization founded in the wake of Sanders' first campaign.

A Turner run would be noteworthy for the amount of money she could potentially raise. Given their close relationship, it's likely Turner would be granted access to Sanders' massive email list, of which many subscribers are already familiar with Turner via her charismatic stump work on the senator's behalf.

Already a resident of the 11th Congressional District, Turner served on the Cleveland City Council prior to being appointed to the state Senate in 2008. She was the Democratic nominee for Ohio secretary of state in 2014, but was defeated by nearly 25 points. Such a defeat would be unlikely in the heavily blue 11th district where the Democratic primary is tantamount to election.

Georgia Secretary of State Brad Raffensperger's office announced Wednesday it has opened an investigation into Coffee County's handling of the election recount.

Raffensperger re-certified the statewide election results on Monday afternoon, after reporters had been told the re-certification would be done the prior Friday. Coffee County was the reason the certification had to be pushed.

While the county's hand audit was off by one vote compared to the county's original results, the machine recount was off by 51 votes. It was possible that the same batch of 50 ballots was inadvertently scanned twice, but the county's election director, Misty Martin, could not say for sure, according to Raffensperger's office.

The county issued a letter that "blamed the voting system for the 51-vote discrepancy, but Ms. Martin could not specify what machine problems were encountered."

The secretary of state's office told Martin she needed to figure out the issue, resolve it, and, if necessary, re-certify the results, but Martin said she wanted to use the election night results, which was not the protocol.

On Friday afternoon, Chris Harvey, the elections director in Raffensperger's office, called Martin, who told him she was experiencing an issue with the scanners. Harvey dispatched a Dominion tech.

Later, when Harvey tried to call Martin back to check on the progress, he couldn't get a hold of her, and later learned from Dominion that the county Board of Elections told Martin to go home and resume working Monday.

On Monday, Raffensperger's office told Martin and the county they needed to resume counting as soon as possible -- not noon as they planned -- because the state needed to re-certify. Martin did that.

"Every other county was able to complete this task within the given time limits," the press release said. "In some cases, counties realized they made mistakes in scanning ballots and had to rescan, or realized they neglected to scan some ballots and had to correct that error. But nonetheless, those counties completed the recount on time."

With just hours to go until Tuesday's "safe harbor" federal law-mandated deadline for states to certify their election results and next Monday's Electoral College voting coming up, time is running out for Trump to find a way to overturn the results of the presidential election as he’s set out to do.

The president held a rally in Georgia -- his first since losing the election -- to campaign for the upcoming Senate runoffs there, races which will determine whether the GOP maintains control, but instead he spent most of his 101 minutes on stage pushing a whirlwind of unsubstantiated claims that the election was stolen.

Trump directly called on GOP Gov. Brian Kemp to "immediately ask for a special session of the legislature" -- which could theoretically set up the process of allowing lawmakers to appoint new electors who would support Trump over Biden despite Biden winning by nearly 12,000 votes in the state.

But Georgia officials have rejected Trump's call.

Kemp, joined by GOP Lt. Gov. Geoff Duncan, said in a statement late Sunday it would be unconstitutional for the legislature to "retroactively change" the process for choosing presidential electors, saying "doing this in order to select a separate slate of presidential electors is not an option that is allowed under state or federal law."

While Kemp and Duncan, along with GOP Secretary of State Brad Raffensperger and officials in his office, have said the only option in disputing the results is through the courts, pro-Trump efforts have ended in at least 38 defeats to date, with only a single court victory -- in a case in Pennsylvania that was ultimately not consequential.

It all comes as the president’s personal attorney tasked with leading his efforts to overturn the election in court, Rudy Giuliani, who has been traveling the country as part of the president's ongoing efforts to dispute election results, remains hospitalized with COVID-19 at MedStar Georgetown University Hospital in Washington since Sunday. The Arizona legislature has closed for the week "out of an abundance of caution" after Giuliani met with roughly a dozen GOP lawmakers.

As deadlines loom, Trump on Monday presents the presidential Medal of Freedom to wrestling legend Dan Gable at noon and meets with Vice President Mike Pence behind closed doors.

And while Trump administration officials vow that with vaccine on the horizon, life will soon return to normal, the Biden team is sounding alarms on its distribution, saying they still don’t have access to the plan to roll it out.

"We have yet to see any kind of detailed plan," Dr. Celine Gounder, an expert on Biden’s COVID-19 advisory board, told "CBS This Morning" Monday after Biden said the same last week.

Pressing forward with the transition despite Trump's roadblocks, Biden and Vice President-elect Harris will receive the President’s Daily Brief and meet with transition advisors on Monday ahead of personally debuting their new health picks, who will inherit leading the country through the ongoing coronavirus pandemic.
