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.

As part of rule debate leading up to debate on the article of impeachment, Republicans have largely focused on procedural concerns, criticizing Democrats for moving quickly to impeach Trump without a full investigation and suggesting the move would further divide Americans.

"I hold him accountable for the attack on the Capitol," newly elected Rep. Nancy Mace, R-S.C., said, making her first speech on the House floor.

"If we're serious about healing the divisions in this country, Republicans and Democrats need to recognize that last week wasn't the first day of violence," she continued. "There is violence on both sides of the aisle."

"President Trump will leave office in seven days," Rep. Jason Smith, R-MO, said. "This is a reckless impeachment ... have a conscience."

Rep. Jim Jordan, R-Ohio, attacked Democrat Rep. Jim McGovern, the chairman of the House Rules Committee, over his 2017 objection to the election results, and accused Democrats of hypocrisy.

McGovern quickly shot back that Democrats and Hillary Clinton recognized Trump's victory -- when Republicans refused to acknowledge Biden's.

"The bottom line is this. This Capitol was stormed -- people died because of the big lies that were being told by this president and by too many other people on this side of the aisle. Enough!" McGovern said. "Coming up on this floor and talking about whataboutism and trying to make these false equivalences -- give me a break."

"The president of the United States instigated an attempted coup in this country," he added. "If this is not an impeachable offense I don't know what the hell is."
