Trump-Biden transition updates: At least 20 arrested, 1 stabbed at DC protests

Trump’s handpicked representative to accelerate vaccine development, Moncef Slaoui, told the Financial Times that Biden’s team should be given access to information on Operation Warp Speed, the federal government’s program for developing and distributing a coronavirus vaccine, so that it is not slowed down. He called it "a matter of life and death for thousands of people." 

The General Services Administration (GSA), headed by a Trump appointee, has yet to officially recognize Biden as the victor in the election, preventing Biden's team from gaining full access to government funds and security information.

Slaoui said he could not make contact with the Biden team without approval from the White House.

Trump spoke publicly for the first time since Biden was projected to win the presidential election with remarks in the Rose Garden Friday afternoon on Operation Warp Speed, the federal government’s program for developing and distributing a coronavirus vaccine. 

Picking up where he left off, Trump didn’t directly address the election, but while speaking about lockdowns he appeared to admit he was uncertain about the future of his administration.

“I will not go -- this administration will not be going to a lockdown. Hopefully, the, the -- whatever happens in the future -- who knows which administration it will be? I guess time will tell, but I can tell you, this administration will not go to a lockdown,” Trump said.

Notably, the Biden team is describing its strategy as a "dimmer switch" -- dialing restrictions up and down in hot spots as needed -- not a lockdown.

Trump did not take any questions from reporters.

Outside the White House, crowds of Trump supporters and counter-demonstrators gathered at Black Lives Matter Plaza ahead of expected rallies from far-right groups in Washington, D.C., on Saturday.

Pennsylvania Secretary of State Kathy Boockvar will not order a recount of the presidential election in the Keystone State, as options for the Trump campaign in its effort to reverse the election results dwindle away.

Boockvar said in a statement Friday that the races for president, state attorney general, auditor general and state treasurer will not face recounts or recanvasses because unofficial returns submitted by the state’s counties showed no statewide candidate lost by less 0.5% -- the margin at which a recount would be triggered.

Trump is currently trailing Biden by more than 60,000 votes in the state.

Arizona's Sen. Martha McSally conceded to Democratic Senator-elect Mark Kelly Friday afternoon, one week after ABC News projected Kelly to be the winner. 

"With nearly all the votes counted, I called Mark Kelly this morning to congratulate him on winning this race," she said in a statement. "I also offered support in his transition to ensure Arizonans are best served during this time."

McSally is currently trailing Kelly by 79,114 votes. Kelly outperformed Biden in the state by nearly 45,000 votes. 

Kelly will serve the remaining two years of late Sen. John McCain's term. McSally was appointed to fill his seat and thanked Arizona Gov. Doug Ducey in the statement.
