Biden fractures foot after fall, will likely be in walking boot 'for several weeks'

Several leading candidates for the roles in president-elect Joe Biden’s administration have come under scrutiny for their work in corporate America or lobbying history.

Michele Flournoy, a leading candidate for the head of the Department of Defense after serving in senior posts at the Pentagon during the Clinton and Obama administrations, has faced criticism from progressive and left-leaning activists for her ties to defense contractors and a strategic advisory firm that has faced questions about its clients.

Several other Cabinet selections and initial White House hires for the Biden administration, along with members of his transition efforts, are under the microscope as well, showing an early struggle between the activist and established wings of the Democratic Party, which collaborated to elect Biden and deny President Donald Trump a second term.

Vice President Mike Pence shared a message of gratitude on Thanksgiving to first responders, military members and health care workers.

“On this Thanksgiving Day, we’re thankful for our Family, Friends & the Doctors, Nurses, First Responders & Men & Women of our Armed Forces that we’ve met along the way. God Bless our Healthcare Workers & our Military, especially those deployed overseas Defending Our Freedom!”

In a message earlier Thursday, the Pence family wished everyone a Happy Thanksgiving on behalf of the vice president and second lady Karen Pence.

After wrapping his teleconference with troops, Trump spoke with reporters. It was the first time he's answered questions since Biden declared victory. 

The president delivered a lengthy list of grievances and unfounded claims of election fraud across the country. 

"It's going to be a very hard thing to concede because we know there was massive fraud," Trump said.

The president provided no direct evidence of fraud while claiming irregularities in Pennsylvania, Michigan and Wisconsin skewed the results in Biden's favor.  He also, again, went after Dominion Voting Systems. 

When asked whether he would announce a run in 2024 if Biden occupies the White House on Jan. 20, the president said, "I don't want to talk about 2024."

Asked if he would leave the White House if Biden is inaugurated, Trump responded, "Certainly, I will. And you know that."

He was also asked whether he would attend Biden's inauguration as tradition dictates.

"I don't want to say that yet. I know the answer, I'll be honest, I know the answer but I just don't want to say it yet," he said.

Trump spoke to military troops via video conference on Thursday from the Diplomatic Room of the White House. 

"My profound thanks to each and every one of you for your devoted service to our nation. Our nation is doing very well. It's the highest honor of my life to serve as your commander in chief," he said, reading from a binder.

He veered off his prepared remarks from time to time to pat himself on the back for ensuring the U.S. did not get involved in any wars during his four years in office and ad-libbed some self-congratulatory remarks about the stock market and vaccine development -- saying the vaccine will be delivered to frontline workers starting next week or the week after next.

"You're doing an incredible job and your country is doing well," he said to the service members, which represented the Army, Navy, Marine Corps, Air Force, Space Force and Coast Guard.

The president also took some questions from reporters and said he would "probably" visit Georgia on Saturday to campaign for the Republican senators who face runoff elections. Trump said it would "most likely be at an airport."

Following the event, the White House indicated that the trip to Georgia would likely occur on Dec. 5.

Earlier on Thursday, Trump visited his golf course in Virginia.
