Biden is headed to Philadelphia today for a follow-up foot scan, two weeks after sustaining small hairline fractures in his mid-foot.

“The president-elect will have a follow-up appointment at the radiology department of the Pennsylvania Hospital,” according to the Office of President-elect Biden.

Biden’s doctor, Dr. Kevin O’Connor, provided more background on the scan in a statement.

“Consistent with our original plan, President-elect Biden will receive routine 2-week post-injury imaging today. This will be performed with a special CT scanner which is able to obtain a “weight-bearing” image. Now that the initial discomfort and swelling are decreased, it is important to observe the structures within the midfoot under the actual pressure of standing. This is the best way to assure ankle and foot stability,” the statement said.

After the scan, O’Connor said: “Weight-bearing CT results were very encouraging. The small fracture in the intermediate cuneiform is barely detectable and the small fracture in the lateral cuneiform is healing as expected. No more extensive injury was identified.”

Biden was spotted as he was leaving the appointment, where he waved and gave a thumbs up to the press corps.

There was a group of people gathered who cheered for Biden. Biden clearly noticed that one man was not wearing a mask and signaled as if to suggest he put one on. The older man just began to blow kisses as the president-elect, according to the TV pooler.

Biden then headed back to Wilmington.

The U.S. Supreme Court late Friday officially put to rest a brazen eleventh-hour attempt by the state of Texas and Republican allies of President Donald Trump to throw out millions of votes in four states and overturn Democrat Joe Biden’s victory in the 2020 presidential election.

In an unsigned, single-page order, the court rejected a lawsuit brought by Texas, citing a lack of standing under Article III of the Constitution. In dismissing the case, the court said Texas had no "cognizable interest" in how Pennsylvania, Michigan, Wisconsin and Georgia conduct their own elections.

The decision, coming just three days before the Electoral College meets to finalize the presidential selection, shut down what Trump had called "perhaps the most important case in history" without the justices getting into the merits of arguments on either side.

House Speaker Nancy Pelosi, D-Calif., excoriated the Supreme Court lawsuit from Texas seeking to overturn the presidential election results in key states, writing in a letter to colleagues on Friday that it is "an act of flailing GOP desperation" which "violates the principles enshrined in our American Democracy."

Quoting the Pennsylvania attorney general's brief calling it a "seditious abuse of the judicial process," she also accused  congressional Republicans who have supported the case of betraying their oaths of office and "subverting the Constitution."

The letter to colleagues comes after at least one Democratic member of the House called on Pelosi to refuse to seat incoming GOP representatives who signed onto the brief.

Biden and Harris formally introduced newly nominated and appointed members of their administration from Wilmington, Delaware, Friday afternoon, showing off several familiar faces, be it from the Obama administration or from Capitol Hill.

For director of the White House Domestic Policy Council, a position which does not require Senate confirmation, Biden picked Susan Rice. Rice served as U.S. ambassador to the United Nations and later as national security adviser in the Obama administration.

In her remarks, Rice laid out the path of her ancestors on both sides who overcame adversity -- a paternal great grandfather who was born a slave in South Carolina and maternal grandparents who immigrated from Jamaica with no education and worked to send their children to college, leading to her mother’s role in creating the Pell Grant.

“Now at the foot of yet another bridge between crisis and opportunity, I'm honored and excited to take on this role. Joe Biden and Kamala Harris's vision for our future is expansive but achievable," Rice said, stressing her excitement to serve again and the need to develop policies that break down racial barriers that hold all Americans back.

Rep. Marcia Fudge, who has represented Ohio's 11th Congressional District for the last 12 years has been tapped for secretary of Housing and Urban Development and talked about the importance of housing in America and the need to give people hope amid  America’s ongoing crisis.

“Perhaps most importantly of all, we will help people believe once again that their government cares about them, no matter who they are. That we understand their problems, as the president-elect often recalls his father's words,” she said.

Biden's nominee for secretary of agriculture, Tom Vilsack, seemed to address some of the criticism of his previous tenure at USDA (he held the same Cabinet position he's nominated for throughout the Obama administration) by promising to deal with systemic inequities.

Vilsack also mentioned his support for Rep. Jim Clyburn's 10/20/30 plan, an effort the South Carolina congressman said aims to help counties that had a poverty level of more 20% for more than three decades. Those communities would receive at least 10% of federal funds from a specific program. When asked in 2019 if he considered the measure a form of reparations, Clyburn said the measure "absolutely" is.

Biden's pick for secretary of veterans affairs, Dennis McDonough, former President Barack Obama's White House chief of staff, pledged to make the department more inclusive to all veterans, particularly women, veterans of color and members of the LGBTQ community.

Biden's appointed Katherine Tai to U.S. trade representative, who began by recalling her parents' immigrant story of her father, a researcher at Walter Reed, and her mother, who still works at the National Institutes of Health developing treatments for opioid addictions. She also stressed the role trade can play to create opportunities and lift people out of poverty and the need to rebuild relationships around the globe.

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.
