Biden fractures foot after fall, will likely be in walking boot 'for several weeks'

In a new video posted to Twitter, President-elect Joe Biden and future first lady Jill Biden talk about their altered Thanksgiving, reminding Americans that while celebrations may be more isolated this year, they are helping keep Americans safe. 

“We have a long tradition of traveling to Nantucket with our big family, a large family, every Thanksgiving. We won't be doing that this year. This year we're going to be staying in Delaware, with just a small group around at our dinner table,” the president-elect said. “I know this isn't the way many of us hoped we'd spend our holiday. We know that a small act of staying home is a gift to our fellow Americans.” 

He continued: “Yes, it's a personal sacrifice that each of our families can make and should make to save somebody else's life. But it's also a shared sacrifice for the whole country, a statement of common purpose that says we care about one another and we're all in this together.” 

The future first lady added that this year, “We’re thankful for the millions of Americans who have been working on the front lines throughout this pandemic.” 

Jill Biden also spoke directly to families who have lost a loved one to the pandemic this year, noting her own family's understanding of the “empty chair” at the table. 

“Joe and I know the pain of that empty chair,” she said. “If you are one of those families, please know that our hearts are with you and that you know that you aren't alone.” 

Finally, Joe Biden urged Americans to come together this holiday.

“We might not be able to join our hands around a table with our loved ones, we can come together as a nation,” he said.

Joe and Jill Biden also penned an op-ed for CNN about the holiday and how this year’s celebration requires large sacrifices to keep the country safe.

Rep. Denver Riggleman, R-Va., said on ABC News' "Powerhouse Politics" podcast that the Republican Party has to move back toward "policies and ideas" and away from conspiracy theories like those about the election.

"I think it's fear of the electorate and the base and maybe those few points that could cost him a primary, not get them reelected or maybe somebody is going to say something mean about them on Twitter," Riggleman said on the podcast.

Riggleman was one of the first Republicans to publicly accept Joe Biden as the president-elect and told ABC News Chief White House Correspondent Jonathan Karl and Political Director Rick Klein that fear of the base was keeping other elected officials from doing the same.

Nevada Gov. Steve Sisolak tweeted Wednesday evening that he signed the certificate of ascertainment, giving Biden electors the highest number of votes. 

"Today, I signed the Certificate of Ascertainment for the slate of electors for Joe Biden and Kamala Harris, as required by federal law," he tweeted, along with photos of the certificates. "I want to thank all the election officials and poll workers who helped facilitate this process in our State." 

He then went on to congratulate those who participated in the democratic process.

On Tuesday the Nevada Supreme Court certified the election results.

Vice President-elect Kamala Harris visited the nonprofit D.C. Central Kitchen with her husband, Doug Emhoff, Wednesday afternoon to thank the staff and volunteers for the work that they were doing. They also passed out individually wrapped cookies.

The nonprofit, which aims to prepare people in need for culinary careers, expects to serve 10,000 meals for the Thanksgiving holiday. Harris also spoke briefly about food insecurity in the U.S. 

"Right now in our country, one in six families are describing their children being hungry. One in five, the last number I saw, can't pay their rent," the vice president-elect said. 

She also spoke about the pandemic, and the isolation many people are feeling "on top of being food insecure." 

"So, to do what you all are doing reminds people that they're not alone," she told the volunteers. "And that's a great gift that you give as well. So, Doug and I wanted to come by just to thank you all, everybody, for what you're doing, and for lifting everybody up."

Harris also took questions, and said that she had not yet spoken to Vice President Mike Pence, but wouldn't answer directly when asked if she had spoken with Senate Majority Leader Mitch McConnell. 

Finally, Harris shared that she and her husband would be spending Thanksgiving in Washington without members of their extended family.
