Trump-Biden transition: Attorney Sidney Powell back at White House Sunday

The Presidential Inaugural Committee, in a new statement Tuesday, has confirmed that Biden and Vice President-elect Kamala Harris will take their oaths of office at the U.S. Capitol in an inauguration that will include "vigorous health and safety protocols" and a "reimagined" parade. 

"Our goal is to create an inauguration that keeps people safe, honors the grand traditions of the Presidency, and showcases the Biden-Harris Administration’s renewed American vision for an inclusive, equitable, and unified citizenry,” said committee CEO Tony Allen in the statement.

Organizers are encouraging people to stay home and not travel to Washington, D.C., for the inauguration as Biden tries to model good public health behavior amid the worsening coronavirus pandemic. The limited festivities will be produced by Stephanie Cutter and Ricky Kirshner, who put together the Democratic National Convention program over the summer. Much like the DNC, the inauguration will have several virtual elements.

Capitol officials have already confirmed that they plan to implement coronavirus testing for everyone expected to come into close contact with Biden and Harris on Jan. 20.

The committee's statement also announced that Dr. David Kessler, a former Food and Drug Administration commissioner who is advising Biden's transition, will be the inaugural committee's chief medical adviser.

Shortly after McConnell called Biden the president-elect for the first time, Senate Minority Leader Chuck Schumer in his floor remarks Tuesday urged the president and other Republicans to follow McConnell's lead. 

"For the sake of the country, President Trump should take his cue from Leader McConnell that it's time to end his term with a modicum of grace and dignity," Schumer said.

"Enough is enough," he continued. "Our Republican colleagues for the sake of our democracy, for the sake of the peaceful transition of power should stop the shenanigans, stop the misrepresentations and acknowledge that Joe Biden will be the next president."

Trump has retweeted conservative attorney Lin Wood, who slammed Georgia Gov. Brain Kemp and Secretary of State Brad Raffensperger on Twitter Tuesday saying, without citing evidence of a crime, that they’re "going to jail."

“President Trump @realDonaldTrump is a genuinely good man. He does not really like to fire people. I bet he dislikes putting people in jail, especially ‘Republicans.’ He gave @BrianKempGA & @GaSecofState every chance to get it right. They refused. They will soon be going to jail," Wood said in the tweet Trump retweeted to his 88 million followers.

Kemp and Raffensperger have both said they are strong supporters of the president and voted for him, but they’ve upheld the integrity of their state's election and have seen no evidence of widespread voter fraud.

An apparently altered photo of the two officials wearing face masks bearing the flag of China accompanied the tweets. 

It’s unclear why Wood believes Trump has the authority to put the two Republicans officials in jail as he suggested. Wood, along with fellow pro-Trump attorney Sidney Powell, filed a lawsuit earlier this month seeking to stop the certification of the state vote and naming Kemp, Raffensperger and other Georgia election officials. The suit has since been dismissed.

Senate Majority Leader Mitch McConnell, the top Republican in Congress, acknowledged Biden’s win for the first time from the Senate floor Tuesday morning after weeks of holding out. 

"Our country has officially a president-elect and a vice-president elect," McConnell said. "The Electoral College has spoken, so today I want to congratulate President-elect Joe Biden."

McConnell also congratulated Vice President-elect Kamala Harris on historic nature of her win.

His acknowledgement comes one day after the Electoral College cemented Biden’s victory. Now that McConnell has accepted the incoming adminstration, it’s expected other Congressional Republicans will fall in line. 

Before McConnell took the floor, Senate Chaplain Barry Black opened Tuesday’s session by saying the Electoral College decision has been accepted and callings for blessings in his opening prayer on "President-elect Joe Biden and Vice President-elect Kamala Harris."
