Composer and playwright Lin-Manuel Miranda is the latest celebrity added to the lineup for the inauguration primetime celebration for President-elect Joe Biden.

A mix of famous faces and everyday Americans will appear throughout the event.

Miranda, who created and starred in the musical "Hamilton," is expected to recite a classic work, according to the Presidential Inaugural Committee. Actresses Kerry Washington and Eva Longoria will introduce segments throughout the program.

Also participating will be Kareem Abdul-Jabbar, the NBA’s all-time leading scorer and chairman of the Skyhook Foundation, Chef Jose Andres, founder of World Central Kitchen, labor leader Dolores Huerta, and Kim Ng, the first woman MLB general manager.

Online vacation rental marketplace Airbnb is reviewing, and potentially canceling, reservations in Lansing, Michigan, ahead of planned protests at the Michigan Capitol building.

“If we confirm that guests are associated with a violent hate group or otherwise not allowed on our platform for violating certain community policies prohibiting violence or engaging in criminal activity, we will cancel those reservations and ban them from Airbnb,” a company spokesperson said. “We are in contact with Governor Whitmer’s team, Mayor Schor and Chief Daryl Green about this plan, and if appropriate, we may bring information to the attention of local law enforcement.”

Airbnb’s efforts in Lansing are similar to its efforts in Washington, D.C. as the company seeks to identify people who have used their site and may pose a risk of violence ahead of planned protests.

“Downtown [Lansing] is a vibrant neighborhood and residents and businesses there should feel confident knowing that the Lansing Police Department is working closely with the Michigan State Police, Ingham County Sheriff’s Department and other police agencies to ensure these planned events remain peaceful,” said Lansing Mayor Andy Schor. “Airbnb has always been a fantastic partner with the U.S. Conference of Mayors, and this effort continues to demonstrate their civic mindedness and high standards of quality."

Residents of downtown Lansing should stay inside and avoid demonstrations, said Schor.

Vice President-elect Kamala Harris kicked off the first night of inaugural events with closing remarks on Saturday during an event titled "America United: An Inauguration Welcome Event Celebrating America’s Changemakers."

Harris noted the work that supporters did to make this moment what it is despite challenges due to coronavirus.

"I'm so excited to officially welcome you to the 59th presidential inauguration," Harris said. "We are here not only to celebrate and mark the start of a new administration, but to honor the work you have done from the primaries to the general election, right up to this very moment -- from Zoom grassroots fundraisers to union meetings on Google Meet to our drive-in rallies -- you were there every step of the way. And on the eve of this inauguration, the president-elect and I thank you for all you have done for our country; we would not be here without you."

Harris shared a message to young Americans to keep fighting and to dream with ambition. She noted that fighting for working people, rooting out systemic racism and combating the climate crisis, while strengthening democracy, are key goals for the administration.

"And I also would not be here without the generations of Americans who struggled and sacrificed to open up opportunity in our country. I stand on their shoulders. And as I've said before, while I may be the first woman to serve as vice president, I will not be the last," she said.

Vice President Mike Pence addressed the incoming Biden-Harris administration during a speech at the Lemoore Naval Air Station in Fresno, California, Saturday.

"As a new American administration prepares to take office, we do well to remember as Americans that the price of freedom is eternal vigilance, and that a free and open Indo-Pacific is essential to our prosperity, our security, and the vitality of freedom in the world," Pence said during his remarks to sailors.

Pence urged the incoming administration to "stay the course" in the region.

"Do what we’ve done," he said. "Stand up to Chinese aggression and trade abuses. Stand strong for a free and open Indo-Pacific and put America and our freedom-loving allies first."

The Trump administration identified China as the greatest long-term threat to the U.S. The Asian nation has shown more assertiveness in the region, including expanding its military presence in the South China Sea.

Biden has said he may keep some of Trump's tariffs in place and expand human rights sanctions, but he's also expected to take a different tact than Trump's "America First" strategy.

Late Friday, Health and Human Services Secretary Alex Azar refuted several media reports that he was resigning early, but did share his resignation letter -- effective Jan. 20 at noon -- on Twitter.

While Azar wrote on Twitter that it was his "duty to help ensure a smooth transition to President-elect Biden’s team during the pandemic" through Inauguration Day, he did criticize President Donald Trump and called on him to more strongly condemn the violence at the Capitol last week.

"Unfortunately, the actions and rhetoric following the election, especially during this past week, threaten to tarnish these and other historic legacies of this Administration," Azar wrote in the resignation letter. "The attacks on the Capitol were an assault on our democracy and on the tradition of peaceful transitions of power that the United States of America first brought to the world. I implore you to continue to condemn unequivocally any form of violence, to demand that no one attempt to disrupt the inaugural activities in Washington or elsewhere, and to continue to support unreservedly the peaceful and orderly transition of power on January 20, 2021."

Azar clarified he handed in the letter, dated Jan. 12, last week "along with every other political appointee."

The two-page letter, in which he calls serving as HHS secretary "the greatest professional privilege and honor of my life," details the administration's response to the coronavirus pandemic. Azar paints an entirely rosy picture, referring to it as a "remarkable response," despite skyrocketing deaths and case rates across most of the nation.

"While we mourn every lost life, our early, aggressive, and comprehensive efforts saved hundreds of thousands or even millions of American lives," he wrote, echoing a refrain from the president. There have been over 391,000 deaths in the U.S., nearly twice the number of the second-highest country (208,000 in Brazil).

He also highlighted the agency's efforts to combat the opioid crisis, electronic cigarettes and the HIV epidemic, and made special mention of "protect[ing] the sanctity of human life from conception to natural death."

Azar has served as HHS secretary since January 2018. President-elect Joe Biden has nominated Xavier Becerra, California's attorney general, to serve as his HHS chief.
