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.

House Democrats have opened an investigation into what law enforcement and the intelligence community knew about threats to the Capitol ahead of the Jan. 6 siege.

The investigation from the House Intelligence, Oversight, Homeland Security and Judiciary committees will also examine whether anyone with security clearances -- current or former National Security, Defense, Justice or Homeland Security officials -- participated in the riot.

The investigation will also examine the federal law enforcement response in the aftermath of the attack.

"The Committees will conduct robust oversight to understand what warning signs may have been missed, determine whether there were systemic failures, and consider how to best address countering domestic violent extremism, including remedying any gaps in legislation or policy," committee members wrote in a letter to the FBI, DHS and Office of the Director of National Intelligence.

"This still-emerging story is one of astounding bravery by some U.S. Capitol Police and other officers; of staggering treachery by violent criminals; and of apparent and high-level failures -- in particular, with respect to intelligence and security preparedness," the letter later stated.

Democrats plan to request documents and briefings from administration officials as part of the investigation -- just one of several looking into the Capitol attack.
