Up against Tuesday's "safe harbor" deadline, Georgia Secretary of State Brad Raffensperger said that he will recertify that Biden won Georgia's election sometime Monday following the state's third recount of the presidential vote there which has Biden ahead by nearly 12,000 votes.

"It's been a long 34 days since the election on Nov. 3. We have now counted legally cast ballots, three times, and the results remain unchanged," Raffensperger told reporters.

As he did in his WSJ op-ed this morning, the secretary equated how former gubernatorial candidate Stacey Abrams acted after her 2018 loss and Trump's behavior in 2020.

"Whether it's the president of the United States or a failed gubernatorial candidate ... disinformation regarding election administration should be condemned and rejected," he said. "All this talk of a stolen election, whether it's Stacey Abrams, or the president of the United States is hurting our state."

Raffensperger also said that "the focus on Nov. 3 is drawing energy away from" the state's goals of job growth, efficient COVID-19 vaccine distribution and "getting back to normal."

"I know there are people that are convinced the election was fraught with problems, but the evidence -- the actual evidence, the facts -- tell us a different story," he said.

Gabriel Sterling, the voting system implementation manager in Raffensperger's office, came to the podium afterward to fact check some of the misinformation that the president has helped spread. In one example, he directly called out the president's legal team for how they've tried to "mislead" people about a video from counting occurring in State Farm Arena in Fulton County that Trump played at his rally in Valdosta on Saturday night.

"What's really frustrating is the president's attorneys had this same videotape. They saw the exact same things the rest of us could see, and they chose to mislead state senators and the public about what was on that video," he said, debunking the notion that there were "magic ballots" that showed up in the state's largest county.

"They knew it was untrue and they continue to do things like this," Sterling said. "We continue to see people who are put in positions of responsibility, sending out this disinformation and undermining the electoral system," he added later.Minutes after Raffensperger told reporters he would receritfy the vote Monday, Trump continued his attacks on election officials in the state on Twitter, targeting GOP Gov. Brian Kemp for signature verification saying he'd have an "easy win" were it conducted -- but signature verification was already done twice for absentee ballots in the state, and the vote was recounted three times affirming Biden's win.

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.

The Biden team has announced co-chairs for the Presidential Inaugural Committee with Democratic Rep. James Clyburn of South Carolina, whose endorsement helped put Biden on a path to victory, at the helm to guide the larger committee as they prepare for the event in 44 days.

"This inauguration will show the country and the world something I have always known: we know Joe, and Joe knows us," Clyburn said in a statement through the Biden transition team.

Rep. Cedric Richmond, D-La., Rep. Lisa Blunt Rochester, D-Del., Los Angeles Mayor Eric Garcetti, and Michigan Gov. Gretchen Whitmer will help lead Biden’s team as co-chairs, along with Clyburn who will serve as chair.

“These leaders reflect the strength, spirit, and diversity of America and have always held a steadfast commitment to restoring the soul of the nation, building back the middle class, and unifying the country,” Biden said in a statement Monday morning.

President-elect Joe Biden unveiled his health team early Monday morning, a slate of seven experts and officials that will lead his administration's response to the ongoing COVID-19 crisis.

California Attorney General and former Rep. Xavier Beccera is nominated as Secretary of Health and Human Services. If confirmed, he would be the first Latino to lead the department.

Vivek Muthy has been nominated to be U.S. Surgeon General, a role he served in during the Obama administration.

Dr. Rochelle Walensky, a leading expert on virus testing, prevention, and treatment, is nominated to serve as director of the Centers for Disease Control and Prevention.

Dr. Marcella Nunez-Smith, one of the country’s foremost experts on health care disparities, will serve as the COVID-19 equity task force chair.

As Biden said last week, Dr. Anthony Fauci will stay on in his current role as as director of the National Institute of Allergy and Infectious Diseases, and will take on the elevated role of Biden's chief medical adviser on the COVID-19 pandemic.

Jeff Zients will serve as coordinator of the COVID-19 response and counselor to the president, and Natalie Quillian will serve as deputy coordinator of the COVID-19 Response.

“This trusted and accomplished team of leaders will bring the highest level of integrity, scientific rigor, and crisis-management experience to one of the toughest challenges America has ever faced — getting the pandemic under control so that the American people can get back to work, back to their lives, and back to their loved ones," Biden said in a statement announcing the picks.

Incoming White House Senior Adviser Louisiana Rep. Cedric Richmond, appeared on CBS' "Face the Nation" on Sunday, but revealed very little about the incoming Biden transition plans for vaccine distribution or dealing with the newly announced investigation of Hunter Biden’s taxes. However, Richmond stressed in his interview that Republicans were very aware that Biden would be president on Jan. 20.

When asked about congressional Republicans largely refusing to recognize President-elect Biden’s victory, Richmond pushed back, saying it was a small portion of the party afraid of Trump.

"They recognize Joe Biden's victory. All of America recognizes Joe Biden's victory. This is just a small portion of the Republican conference that are appeasing and patronizing the President on his way out because they are scared of his Twitter power and other things. And so when it's time to govern, if we can't cooperate -- if Republicans won't meet us halfway, we will go to the American people, and we will continue to push our agenda. But this country is in far too much turmoil. And this pandemic, the economic aspects and health aspects really caused for America to get on one page -- solve this crisis and start to move forward. So -- we're not going to let them slow us down,” he said.

"I talk to Republican members of Congress all the time, and they say one thing privately, they say another thing publicly. But the one thing I will tell you is they realize he lost this election," Richmond added.
