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.

Addressing the coronavirus pandemic, confronting the climate crisis and building public trust in science and technology will be among the Biden administration's key areas of focus, the president-elect said during a press briefing introducing four key members of his science team.

Building back the economy "to ensure prosperity is fully shared all across America" and ensuring the U.S. "leads the world in technologies and industries that the future" will also be a focus, Biden said Saturday during an address in Wilmington, Delaware.

Helping lead those initiatives will be Eric Lander, the presidential science advisor-designate, a position that for the first time will be a cabinet rank, Biden noted.

"I've always said that the Biden-Harris administration will lead with science and truth," Biden said. "We believe in both. This is how we're going to, God willing, overcome the pandemic and build our country back better than it was before. That's why for the first time in history, I'm going to be elevating the presidential science advisor to a Cabinet rank, because we think it's that important."

Frances Arnold and Maria Zuber will be at the helm of the first all-women team to lead the President’s Council of Advisors on Science and Technology.

Alondra Nelson will also be deputy director for science and society for the Office of Science and Technology Policy.

Dr. Francis Collins, who was not present at the event, will also continue in his role as director of the National Institutes of Health.Biden thanked him for "being willing to stay on," saying that it wasn't his original plan.

"I've known Dr. Collins for many years. I worked with him closely," Biden said, accling him "brilliant, a pioneer, a true leader."

"This is the most exciting announcement that I have gotten to make in the entire Cabinet," Biden said of his picks. "These are among the brightest, most dedicated people, not only in the country but the world."
