Trump-Biden transition updates: At least 20 arrested, 1 stabbed at DC protests

House Speaker Nancy Pelosi, D-Calif., slammed Republicans on Friday for not accepting the election results and, she said, "making it even harder to address the massive health and economic crisis facing America."

"The longer the Republicans keep up the charade, the further out of control the COVID crisis with spiral, and more endangered Americans will be," Pelosi told reporters on Capitol Hill. 

The House Speaker also fielded questions about House Democrats' poor performance in the election that could give them the slimmest majority in the House in decades. She claimed Democrats always knew it would be tough to hold onto seats won in Trump districts two years ago, even though she and her team predicted they would expand their majority this year.

"We're getting ready already for the next time, a number of our candidates have said they're going to run again," she said of the losing Democrats.

Asked if she took responsibility for the losses as she left the the press conference, Pelosi said, "I take responsibility for winning the majority."

After a week of Trump campaign staffers answering a "voter fraud" hotline as Trump's team continues to search for evidence of voter fraud, the number is no longer operational, and the campaign is now directing people to its online form instead, multiple sources tell ABC News.

As ABC News reported, that hotline was getting flooded with prank calls, and lewd images were being sent through the online form set up to collect voter fraud claims.

The news comes as the Trump campaign is significantly downsizing staff starting next week with only a small number of staffers receiving an extension through the end of the month, multiple sources said.

As the balance of power in the Senate -- and Biden's subsequent ability to pass the big-ticket legislation he's hoping for -- hangs on two election runoffs in Georgia, Republicans are rallying to "Defend the Majority” as Democrats see promise in the purple state.

On Friday, Florida Sen. Rick Scott, a Republican and vocal ally of Trump’s, is joining GOP incumbent Sens. David Perdue and Kelly Loeffler for an afternoon rally in Cumming, Georgia. Earlier in the week, Republican Sen. Marco Rubio of Florida joined Loeffler to kick off her runoff campaign at an indoor rally.

Loeffler is facing a challenge from Rev. Raphael Warnock, senior pastor at the historic Ebenezer Baptist Church in Atlanta, while Purdue is facing Jon Ossoff, who nearly flipped Georgia’s 6th Congressional District for Democrats in a special election in 2017. 

The runoff elections will be held on Jan. 5.

Biden issued a statement Friday morning remembering the five-year anniversary of the ISIS terrorist attacks in Paris and pledging to restore and improve cooperation with allies as president.

“This was an assault not just on the people of Paris but against our common humanity and shared values,” Biden wrote. “My administration will work steadfastly to protect the safety and security of Americans and our allies and partners, countering terrorism and extremist violence in all of its forms -- no matter the ideology or origin.”

While Trump has taken an isolationist approach to foreign policy, pushing the slogan, "America First," Biden ran -- and won -- on a platform of restoring relationships with foreign allies.
