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.

Biden outlined the major points of his rescue plan: a $1.9 trillion proposal that includes a nationwide vaccination program, $1,400 checks for individuals, an extension and expansion of unemployment benefits and help for struggling communities and businesses.

Biden placed particular emphasis on housing and food insecurity and spoke about expanding SNAP benefits. He said his policy plan would extend the eviction and foreclosure moratorium, potentially previewing an executive action we could see next week. He also asked Congress to appropriate funds for rental assistance.

Biden, who preached bipartisanship while on the trail, said both he and Vice President-elect Harris had spoken with officials, mayors, and governors of both parties on a regular basis to address the problems across the country.

The president-elect also emphasized his plan's focus on helping small businesses and minority-owned businesses in particular, criticizing the Trump administration's initial approach which he said favored the wealthy and well-connected.

"Last week, I laid out how we'll make sure that our emergency small business relief is distributed swiftly and equitably, unlike the first time around. We're going to focus on small businesses, on Main Street. We'll focus on minority-owned small businesses, women-owned small businesses, and finally having equal access to the resources they need to reopen and to rebuild," Biden said.

He also pushed his plan for a mandatory federal minimum wage of $15 an hour.

"People tell me that's going to be hard to pass. Florida just passed it, as divided as that state is, they just passed it. The rest of the country is ready to move as well," he said. "No one working 40 hours a week should live below the poverty line. And that's what it means. If you work for less than $15 an hour and work 40 hours a week, you're living in poverty."

He frankly noted the "bold, practical" policy he was putting forward did not come cheap but argued there was no option to act.

"I know what I just described does not come cheaply. But failure to do so will cost us dearly," he said. "The consensus among leading economists is we simply cannot afford not to do what I'm proposing."

Biden ended his remarks with a call for unity and optimism, referencing his inauguration on Wednesday as a "new chapter for the country."
