Lady Gaga and Jennifer Lopez will lend their voices to Biden's inauguration next week, performing when he officially becomes the 46th president of the United States, Biden's Presidential Inaugural Committee announced Thursday morning.

The announcement detailing participants in the 59th inaugural swearing-in ceremony represents one of the more traditional aspects of Biden's inauguration, which has been largely altered amid the COVID-19 pandemic to accommodate an at-home audience, and facing new concerns over security in the wake of a riot at the Capitol last week that left five dead.

Gaga, who appeared on the campaign trail with Biden during the 2020 election and worked with the then-vice president on his "It's on Us" campaign to combat campus sexual assault, will perform the national anthem when Biden is sworn in, the committee announced.

Lopez, who endorsed Biden, and took part in a virtual chat with the president-elect during the campaign, is also slated to perform at the event.

Ten is either a huge number or a stunningly small one, depending on one's views of the state of partisanship and Trump's culpability for his words and actions.

But 10 Republicans won't be enough to bring true consequences to the soon-to-be-former president. That will fall to the Senate, where the focus will be in the early days of the Biden presidency, now that the House voted in the quickest and most bipartisan impeachment in American history.

Senate Majority Leader Mitch McConnell is making clear that impeachment will be Senate Minority Leader Chuck Schumer's to handle, once they trade jobs late next week. McConnell's public statement not to have prejudged the outcome matters greatly at the outset of the coming trial.

All of the dynamics will be different by this time next week. Soon-to-be-President Biden will have appointees to confirm and a COVID-19 relief bill he wants passed; more will emerge about how last Wednesday's indignities came to pass; and the nation will know whether Biden will be allowed to take office peacefully in the end.

Plus, the Senate is just different than the House. There are different personalities and election cycles, different ambitions, more and different potential coalitions and partnerships, and an overall sense of more independence from presidents.

Trump's legacy has been sullied by the events of the past week and a second impeachment leaves its own permanent mark. But final and official judgments will fall to the body Biden knows so well -- and where he is likely to look to build his own presidential legacy starting quite soon.

Although South Dakota Rep. Dusty Johnson said that Trump deserves “more than his fair share of blame” for the U.S. Capitol riot last week, he voted not to impeach the president Wednesday.

Johnson told ABC News that his decision was based on due process of the law.

“I think due process matters,” said Johnson. “I just felt like a snap impeachment was not in the best interest of the country.”

He said Trump could have been held accountable through censure.

“Impeachment for someone who is out of office looks like some sort of formal reprimand. Really, you can’t kick them out when they’re already gone,” said Johnson. “I think (Nancy Pelosi) could have gotten 100 Republican votes for censure.”

Democrats defended the use of impeachment because an impeachment and a conviction vote by two-thirds of the Senate would open Trump up to a congressional ban on running for federal office. Trump has already indicated that he would run for office again in 2024.

Johnson said that he and “dozens” of his Republican colleagues felt frustrated on the House floor Wednesday. He said that his fellow Democrats missed an opportunity to work across the aisle.

“The rhetoric on the House floor today was the most toxic I have seen in my two years. It was the most rancorous,” he said. “And that’s one of the reasons why I was trying to get some of my Democratic colleagues more interested in a bipartisan censure, a more unifying approach than, I think, a largely single-party impeachment process.”

For the third time in less than a year, the acting Immigration and Customs Enforcement (ICE) director has resigned, according to a source familiar with the matter.

Jonathan Fahey only lasted two weeks on the job.

Fahey is the third acting ICE director in less than a year. The previous director, Tony Pham only lasted a couple of months.

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."
