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.

Although South Dakota Rep. Dusty Johnson said that Trump deserves “more than his fair share of blame” for the U.S. Capitol riot last week, he voted not to impeach the president Wednesday.

Johnson told ABC News that his decision was based on due process of the law.

“I think due process matters,” said Johnson. “I just felt like a snap impeachment was not in the best interest of the country.”

He said Trump could have been held accountable through censure.

“Impeachment for someone who is out of office looks like some sort of formal reprimand. Really, you can’t kick them out when they’re already gone,” said Johnson. “I think (Nancy Pelosi) could have gotten 100 Republican votes for censure.”

Democrats defended the use of impeachment because an impeachment and a conviction vote by two-thirds of the Senate would open Trump up to a congressional ban on running for federal office. Trump has already indicated that he would run for office again in 2024.

Johnson said that he and “dozens” of his Republican colleagues felt frustrated on the House floor Wednesday. He said that his fellow Democrats missed an opportunity to work across the aisle.

“The rhetoric on the House floor today was the most toxic I have seen in my two years. It was the most rancorous,” he said. “And that’s one of the reasons why I was trying to get some of my Democratic colleagues more interested in a bipartisan censure, a more unifying approach than, I think, a largely single-party impeachment process.”
