Biden confirmed more Cabinet picks are expected to come this week, saying he would announce his Defense Secretary on Friday.

While Biden rolled out a portion of his national security team as part of his first Cabinet announcement, there has been continued speculation over his choice to lead the Justice and Defense Departments. Biden in recent days has been urged to appoint a person of color, particularly a Black person at the Department of Defense and as the Attorney General.

The speculation comes ahead of Biden meeting with the NAACP on Tuesday.

Biden has arrived at The Queen Theater in Wilmington, Delaware, his de facto transition headquarters ahead of his inauguration in 44 days again without a medical accessory he's donned for the larger part of the last week.

Although Biden's doctor said last Sunday he would likely be wearing a walking boot for "several weeks" after he sustained hairline fractures in his right foot, Biden was not wearing the boot when he walked into the theater Monday afternoon. While attending a Saturday Mass in Wilmington, he was also spotted without what Biden has referred to as "the big boot."

Biden has said his foot feels “good” despite sustaining the fractures just over a week ago, and addressed the boot issue during an interview with CNN Thursday, noting that the larger cast is a little clumsy and while he wears it "most of the time," he’s been given a smaller option for going out in public.

Biden will receive the President’s Daily Brief and meet with transition advisers on Monday, according to his public schedule, and pre-tape transition production elements at The Queen, his team said.

It comes ahead of Biden introducing his top health care picks to the public on Tuesday including California Attorney General Xavier Berecca to lead the Health and Human Services Department and Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, as Biden's chief medical adviser to lead the country through the worsening COVID-19 pandemic.

Secretary of State Brad Raffensperger has recertified the results of the 2020 presidential election following a second audit that entailed counties counting by hand every one of the approximately 5 million ballots cast in the race.

The Trump campaign requested a recount after votes were first certified for Biden on Nov. 20, but the machine recount, as officials said to expect, reaffirmed that Biden won Georgia's 16 electoral votes -- the first Democratic presidential victory in the state since 1992.

In a press release announcing the recertification, Raffensperger also gave a statement about the dismissal of former Trump legal team lawyer Sidney Powell's "Kraken" lawsuit by a Georgia court earlier in the day.

“Today is an important day for election integrity in Georgia and across the country,” Raffensperger said. “The claims in the Kraken lawsuit prove to be as mythological as the creature for which they’re named. Georgians can now move forward knowing that their votes, and only their legal votes, were counted accurately, fairly, and reliably.”

A Trump campaign lawsuit was rejected by a Georgia state court Monday because the Trump legal team failed to pay the filing fee and neglected to fill out the proper forms. It's the latest in a string of blunders and gaffes that are adding self-inflicted delays to their time-sensitive legal challenges.

Trump filed the lawsuit in Georgia Friday afternoon officially contesting the results of the election and requesting a do-over -- another in a series of long-shot legal bids that have so far met with stiff resistance from the state's Republican election officials. Pro-Trump legal efforts across the country 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.

The latest rejection comes just after Georgia Secretary of State Brad Raffensperger said he would recertify the state’s election results, affirming Biden’s victory after a third count of presidential votes, sometime Monday.

A day after the U.S. Supreme Court denied Texas' challenge to Biden's 2020 presidential election victory, Trump supporters gathered in Washington, D.C. to protest alleged voter fraud.

The "March for Trump" event, which started at noon on Saturday, includes a march to the U.S. Supreme Court to "demand transparency and protect election integrity," according to promotional materials.

Former Trump administration national security adviser Mike Flynn was among those in attendance.

Trump tweeted Saturday morning that he just found out about the rally and said "I'll be seeing them."

On Friday, the Supreme Court rejected a lawsuit brought by the state of Texas and Republican allies of Trump to throw out millions of votes in four states and overturn Biden's victory. In dismissing the case, the court said Texas had no "cognizable interest" in how Pennsylvania, Michigan, Wisconsin and Georgia conduct their own elections.

The rally also comes as members of the Electoral College will meet Monday to formally cast their votes for president.
