During a news conference Friday, D.C. Mayor Muriel Bowser said the National Mall is temporarily closed to the public through at least Thursday.

Thirteen metro stations inside the security perimeter will also be closed.

Bowser said the National Mall closure came at the request of and in cooperation with the Secret Service and the National Park Service.

The mayor urged Americans to enjoy the inauguration virtually from home this year.

She also discussed the city’s beefed-up security ahead of the inauguration but told D.C. residents she doesn’t expect the security measures currently in place to last too long after Biden takes office.

The nomination hearing for Biden’s pick for director of national intelligence, Avril Haines, has been postponed. It was originally scheduled for Friday.

A joint statement from Senate Intelligence Committee Acting Chairman Marco Rubio and Vice Chairman Mark Warner on Thursday confirmed the postponement. It did not give specific reasons, but referenced the “unusual circumstances on Capitol Hill.”

Rubio and Warner added that they "look forward to holding a hearing next week" for Haines, but did not list a specific date.

Far from a one-off event, the Jan. 6 siege at the Capitol emboldened extremists and “is very likely part of an ongoing trend,” according to a joint intelligence bulletin obtained by ABC News.

The trend involves domestic extremists exploiting lawful gatherings to engage in violence and criminal activity and the bulletin said that “very likely will increase throughout 2021.”

Targets include racial, ethnic and religious minorities along with journalists and government officials.

“Narratives surrounding the perceived success of the 6 January breach of the US Capitol, and the proliferation of conspiracy theories will likely lead to an increased [domestic violent extremist] threat towards representatives of federal, state, and local governments across the United States, particularly in the lead-in to the 20 January Presidential Inauguration,” the bulletin said.

Beyond the inauguration, the bulletin said gun control legislation, the easing of immigration restrictions and limits on the use of public land could antagonize extremists.

There is a range of groups that share what the bulletin called the “false narrative of a stolen election.”

“In-person engagement between domestic violent extremists of differing ideological goals during the Capitol breach likely served to foster connections, which may increase DVEs’ willingness, capability, and motivation to attack and undermine a government they view as illegitimate,” the bulletin said.

In a series of tweets Friday, incoming White House press secretary Jen Psaki provided some information on the structure of the Biden administration's vaccination effort and confirmed that the program will not go by the "Operation Warp Speed" name created by the Trump administration.

Psaki also said that Bechara Choucair, previously announced as the Biden team's vaccination coordinator, will lead the 100 million doses delivered in 100 days effort, while Dr. David Kessler's role will focus on maximizing the current supply of vaccine and to get more online as quickly as possible.

Rep. Steve Scalise, R-La. -- the No. 2 Republican in the House -- was the last to speak for the Republican Party, said he opposed the "rushed" impeachment, and emphasized that the Senate will only be able to take up the trial once Trump is out of office.

"I've seen the dark evil of political violence firsthand. And it needs to stop. But all of us need to be unequivocal in calling it out every single time we see it, not just when it comes from the other side of the aisle," he said.

Invoking President Abraham Lincoln, he closed by calling on Americans to unify and "seek higher ground."

House Judiciary Chairman Rep. Jerry Nadler, D-N.Y., quickly responded to his remarks, saying, "We can have all this, and we can have accountability too," before handing off to Majority Leader Rep. Steny Hoyer, D-Md.

Hoyer, in a scathing rebuke of the president, repeated the words of Rep. Liz Cheney and called on his Republicans colleagues to rise to the moment and join her to "reject the vices we abhore."

"It is the first and only physical presence other than the 9/11 attack on this nation -- which came from abroad with a plane aimed at our Capitol dome. This attack was not from abroad. It was as Liz Cheney said, summoned, assembled, and inflamed by the president of the United States of America," he said.

"Last Wednesday, on Jan. 6, the nation and the world watched it shatter to pieces. There could be no mistaking any longer the kind of man sitting in the Oval Office or his intentions and capabilities. The curtain has been pulled back. The office to which he was elected could not temper or reform him," Hoyer said.

"Reject deceit. Reject fear mongering. Reject sedition, tyranny and insurrection," Hoyer said. "Reject one man over fidelity to one's country."

Hoyer noted that soon the House Reading Clerk will call the roll for voting, and added, "Make no mistake, this will be no ordinary roll call."

"These votes will be inscribed on the roll of history -- a record of courage -- and of our commitment to country and Constitution, of our commitment to the rule of law and renewal of that which we inherited and hope to pass on, unbroken, unshattered," he said. "Vote for this -- for America, for our constitution, for democracy, for history."
