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

In his first appearance since the transition became official, Trump spoke for just 66 seconds in the White House briefing room about the Dow Jones Industrial Average trading above 30,000. 

He made no reference to the election or the GSA, and made only a passing reference to the pandemic.

The president refused to take shouted questions from reporters during the brief news conference. This marks the 21st day in a row that the Trump has refused to take questions from reporters, despite continuing to promote baseless conspiracy theories about the election on Twitter."

The stock market’s just broken 30,000. Never been broken, that number," Trump said. "I just want to congratulate all the people within the administration that worked so hard."

Notably, Trump was singing a very different tune Tuesday than he did while campaigning when he repeatedly warned that the stock market would “crash” if Biden won the election.

“If he is elected, the stock market will crash,” Trump said during an Oct. 22 debate.

In reality, markets have rallied sharply since Trump lost the election.

President-elect Biden's transition team began reaching out to federal agencies on Monday night, soon after receiving the green light from the GSA and its embattled Administrator Emily Murphy. 

Some of the more than 500 Biden staffers and volunteers organized into agency review teams are already in the process of scheduling additional briefings and meetings with counterparts at the Justice Department, Pentagon, Centers for Disease Control, and Department of Health and Human Services, according to a transition official. 

Under normal circumstances, those teams would be fanning out across the Washington, D.C., area to meet with officials at each agency and gather in their own office space set aside for presidential transition work. But most of Biden's operation is expected to continue working remotely, given the pandemic, though exceptions include team members working in the national security space, who will need to access classified information in secure settings.

As for Biden, the president-elect could receive his first presidential daily brief -- the sensitive intelligence document seen by only a handful of senior administration officials along with the commander-in-chief -- in the coming days.

After Pennsylvania certified its election results, the lead attorney for the Biden campaign, Bob Bauer, again lambasted the Trump team’s legal efforts. 

"It's readily apparent to everyone besides Donald Trump, Rudy Giuliani, and Jenna Ellis that this election is over and that Joe Biden won resoundingly,” Bauer said in a statement. “Trump did everything he could to disenfranchise voters and stop the results from being certified in Pennsylvania, including filing over 15 unsuccessful lawsuits -- most recently producing one of the more embarrassing courtroom performances of all time, with the judge in the case ruling that their arguments were 'without merit' and 'unsupported by evidence.’” 

Bauer added that Trump "did not succeed in Pennsylvania and he will not succeed anywhere else."

Finally, he said that the Trump team’s lawsuits will "continue to fail" and Biden will be sworn in as president on Jan. 20, 2021.

Pennsylvania announced this morning that the results of the presidential election in the state have been certified, giving Biden the state's 20 electoral votes.

All 67 of the state's counties submitted their results late last night, and after certification by state Secretary of State Kathy Boockvar, Gov. Tom Wolf signed the Certificate of Ascertainment for President-elect Biden and Vice President-elect Harris' electors.

The final vote totals were 50% for Biden and 48.8% for Trump.
