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.

Eva Longoria, Kerry Washington, the Foo Fighters, John Legend and Bruce Springsteen have joined the growing list of celebrities who will appear at the star-studded event celebrating Biden's inauguration next week.

The event, hosted by Tom Hanks, will be a primetime television special that will air the night after the swearing-in ceremony at the U.S. Capitol on Jan. 20.

Longoria and Washington "will introduce segments throughout the night ranging from stories of young people making a difference in their communities to musical performances," Biden's inaugural committee said in a statement Friday.

Meanwhile, the Foo Fighters, Springsteen and Legend will perform remotely "from iconic locations across the country, joining Demi Lovato, Justin Timberlake, Ant Clemons and Jon Bon Jovi with additional performances to be announced ahead of January 20," the committee said.

The committee had previously announced that Lady Gaga will sing the national anthem while Biden and Harris are sworn in. Jennifer Lopez will also give a musical performance.

House Speaker Nancy Pelosi, D-Calif., said Friday that "our managers are solemnly and prayerfully preparing" for Trump's impeachment trial, "which they will take to the Senate."

"Justice is called for as we address the active insurrection that was perpetrated against the Capitol complex last week," Pelosi said during her weekly press conference at the U.S. Capitol Visitor Center in Washington, D.C.

Pelosi did not specify when the article of impeachment will be sent to the Senate, prompting the trial. According to Senate rules, the trial would begin the day after the impeachment charge is sent over by the House of Representatives.

"You'll be the first to know when we announce that we're going over there," she told reporters.

Pelosi noted how quickly the House voted to impeach the president, just one week after the Jan. 6 attack on the U.S. Capitol, which she said was "incentivised" by Trump.

"So urgent was the matter," she told reporters.

When asked about the role members of Congress may have played in the riot, Pelosi said they would be held accountable.

"If it in fact it is found that members of Congress were accomplices to this insurrection, if they aided and abetted the crime," she said, "there may have to be actions taken beyond the Congress in terms of prosecution."

The speaker also announced that she's asked retired Lt. Gen. Russel Honore -- who helped coordinate the military relief efforts after Hurricane Katrina -- to lead an "immediate review" of security failings at the Capitol, reviewing security infrastructure, the interagency process, and command and control.

At the start of Friday's press conference, Pelosi quoted Martin Luther King Jr., saying, "True peace is not merely the absence of tension; it is the presence of justice."

The FBI, DHS, Secret Service and U.S. Capitol Police, along with several local law enforcement agencies, have issued an extensive "threat assessment" surrounding Wednesday's inauguration.

It covers a range of threats surrounding the inauguration, including not only physical threats from domestic terrorists but also influence campaigns from Russia, China and Iran stemming from the Capitol siege. It even covers physical threats from drones.

The memo says domestic extremists is the “most likely” threat to the inauguration, citing recent incidents of ideologically motivated violence, including the deadly mob at the U.S. Capitol building.

Regarding foreign concerns, the assessment said that since the incident at the Capitol, “Russian, Iranian, and Chinese influence actors have seized the opportunity to amplify narratives in furtherance of their policy interest amid the presidential transition.”

“We have not identified any specific, credible information indicating that these actors intend to explicitly commit violence,” it added. “Furthermore, we have not identified any specific, credible cyber threat to critical infrastructure supporting the upcoming Presidential Inauguration nor a specific credible cyber threat to military or law enforcement personnel supporting the event."

The memo did say, however, that Russian state media has “amplified themes related to the violent and chaotic nature of the Capitol Hill incident, impeachment of President Trump, and social media censorship.”

Iranian state media has “continued to stoke claims that President Trump encouraged and incited the violence, as well as calls to invoke the 25th amendment,” the memo added. It has also “amplified perceived concerns related to President Trump’s mental health and the prospect of other risky actions he could take before leaving office.”

Finally, it noted that Chinese media has “seized the story to denigrate US democratic governance -- casting the United States as broadly in decline -- and to justify China’s crackdown on protestors in Hong Kong."

Lastly, the memo warned that drones could disrupt law enforcement operations at the inauguration, though it added that it does not have “specific, credible information” indicating malicious actors have plans to use unmanned aircraft systems to target the event.
