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."

Biden and Vice President-elect Kamala Harris have announced additional White House picks -- with many familiar faces from Biden's 2020 campaign staff.

While she was not expected to join the administration and instead return to her communication’s firm SKDKnickerbocker, Anita Dunn will be serving as a senior adviser to the president -- marking yet another longtime Biden adviser and a member of the highest echelons of his campaign joining the White House in a senior role.

TJ Ducklo, the national spokesperson for the campaign, will also join the White House as deputy press secretary alongside Karine Jean-Pierre. Deputy press secretary Matt Hill will join as a senior associate communications director.

Biden’s campaign photographer and videographer will also take on similar roles in the administration.

The House of Representatives' Committee on Oversight and Reform has sent letters to two dozen hotels and private travel companies seeking help in identifying rioters and preventing future attacks in Washington, D.C., ahead of Biden's inauguration.

"While the inciters and attackers bear direct responsibility for the siege on the Capitol and will be held fully accountable, they relied on a range of companies and services to get them there and house them once they arrived—companies that law-abiding Americans use every day, but whose services were hijacked to further the January 6 attacks," committee chairwoman Rep. Carolyn Maloney, D-N.Y., wrote in the letters. "Trump supporters chartered scores of buses and vans and drove in caravans to the nation’s capital. They stayed in D.C. hotels, with videos showing attackers relaxing in the lobby of one hotel after the insurrection."

The committee has asked the businesses -- ranging from major hotel chains to bus and car rental companies -- to retain records of January reservations for future congressional investigations, to put in place additional screening measures "to ensure that your services are not being used to facilitate violence or domestic terrorism," and to provide information to the committee by Jan. 29 on those measures.

Senate Majority Leader Mitch McConnell has privately acknowledged he believes Trump committed impeachable offenses and that he is pleased Democrats are moving to impeach him, believing it will make it easier for the Republican Party to be rid of Trump, a source confirmed to ABC News.

The New York Times first reported the development.

McConnell has not said publicly whether he'd vote to impeach Trump and a McConnell spokesman declined to comment.

At least three House Republicans -- Rep. Liz Cheney, Wyo., Rep. John Katko, R-N.Y. and Rep. Adam Kinzinger, R-Ill. -- have said they will vote to impeach the president.
