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.

President Trump, one week ago, encouraged thousands of his supporters to march on Capitol Hill, firing them up with baseless claims of election fraud and instructing them to "fight like hell" in order to "stop the steal,” while Congress affirmed Biden’s electoral vote victory. That day ended in a violent attack on one of the most revered buildings in America.

One week later, Trump finds himself on track to become the first president in American history to be impeached twice as the House of Representatives is scheduled to convene at 9 a.m. Wednesday to debate a rule, then debate on one article of impeachment charging the president with "incitement of insurrection." A final vote is expected later in the day.

Republicans are expected to argue Trump's rhetoric ahead of the mob Wednesday doesn't arise to an impeachable offense, and Democrats are expected to blast those 139 House Republicans who still objected to election results after the roughly six-hour siege.

With at least 218 House Democrats and five House Republicans announcing they’ll vote to impeach the president, a trial in the Senate is imminent. Half of the country's presidential impeachment trials will then belong to Trump.

While House Speaker Nancy Pelosi has not publicly indicated when the House would send the article of impeachment to the Senate after its expected passage, she plans to send it to the Senate next week, according to a source involved in the Democratic leadership deliberations on the matter.

Senate Majority Leader Mitch McConnell has said already he won't bring back the Senate from recess before Jan. 19 -- a day before Biden's inauguration. While McConnell has not said if he would vote to convict or whether he'd hold a trial in the Senate, ABC News has learned, he has privately indicated he believes impeaching Trump could make it easier to rid the Republican Party of Trumpism.

Branding his presidency as a "time to heal," both Biden and Vice President-elect Kamala Harris have deflected impeachment questions to Congress.-- but with confirmations for Cabinet picks and priorities to pass additional coronavirus relief potentially coinciding with Trump’s impeachment trial in the Senate, it’s unclear how Biden -- or the U.S. Senate -- will divide their agendas.
