Trump campaign disavows lawyer Sidney Powell: Transition updates

Following his remarks on economic recovery, Biden took questions largely focused on his transition of power as Trump still refuses to recognize Biden as the president-elect.

Asked what’s the biggest threat to his stalled transition, Biden said the ability to coordinate on a pandemic plan as cases surge across the country. 

“More people may die if we don't coordinate,” Biden said. “If we have to wait until Jan. 20 to start that planning, it puts us behind over a month, month and a half.”

Questioned by ABC News Chief Congressional Correspondent Mary Bruce what he plans to do about the Trump administration’s stone-walling, Biden said he will continue to engage with stakeholders across the spectrum but acknowledged that it would “make it a lot easier” if Trump would cooperate.

When pressed on his message to Republicans who are also refusing to recognize him as president-elect, Biden said he would still work with them but called it a “shame” if his team had to wait until Jan. 20 to access federally appropriated transition resources. 

“I will work with you. I understand a lot of your reluctance because of the way the president operates,” Biden said. “If it has to wait until Jan. 20 to actually become operational, that's a shame, but maybe -- maybe that's the only way to get it done.”

“As I said earlier -- and I probably shouldn't repeat it, but I find this more embarrassing for the country than debilitating for my ability to get started,” Biden said about Trump's weekend tweets where he first seemed to acknowledge Biden won but then said he wouldn't concede.

Biden again urged Congress to pass the Heroes Act, the House-passed COVID-19 relief legislation that Senate GOP leadership has not brought up for a vote, saying the federal government has all the money and capacity to deliver more relief now.  

“The idea the president is still playing golf and not doing anything about it is beyond my comprehension,” Biden said. “You’d at least think he'd want to go off on a positive note.”

Following an economic briefing with labor and business leaders, Biden and Harris delivered remarks on economic recovery amid the pandemic and in the long-term.

Harris was the first to speak and stressed the "necessary work" of getting the pandemic under control, as she and Biden have emphasized the pandemic and economy are intertwined.

"The road ahead, it will not be easy. But the president-elect and I are hitting the ground running because we all know the challenges facing America today are great. The American people deserve no less. And we don't have a moment to waste," she said, introducing Biden.

Biden said their earlier conversation with American union leaders and business executives reinforced his belief that representatives from across the aisle are ready to come together to combat the virus to "Build Back Better," hearkening back to an early campaign slogan.

"I wish you could have heard corporate leaders and major labor leaders singing from the same hymnal here," Biden said, touting his ability to bring the groups together. 

Biden went on to praise the vaccine news from Moderna and Pfizer but warned that developing the vaccine and distributing it to Americans are two different issues. 

As the Trump administration still hasn't recognized Biden as the president-elect, preventing his access to federally allocated transition resources, Biden said every representative at the economic briefing agreed that the sooner Biden has access to the administration's vaccine distribution plans, the smoother the transition -- for the benefit of the American people.

He also called on Congress to pass the Heroes Act, the House-passed COVID-19 relief legislation which Senate GOP leadership has not brought up for a vote, before broadening his remarks on how he would make the economy work better for Americans from all walks of life. 

It was the pair's first joint economic-focused remarks since they were projected to win the election. The remarks came more than an hour after they were scheduled to begin speaking, from The Queen Theater in Wilmington, Delaware, on Monday afternoon.

Biden opened the floor for questions following the remarks.

Maryland Gov. Larry Hogan, an outspoken critic of the president's who previously revealed he voted for Ronald Reagan in this year's election, is urging Trump to admit defeat and move forward with a peaceful transition for his successor.

"Like it or not, I mean, the president didn't win and so now, you know, we have Joe Biden as president for four years," he said at a forum hosted by the Ronald Reagan Institute. "Tomorrow will be two weeks. ... The time has come," he added in response to when Trump should concede.

The self-described "Reagan Republican" also underscored the urgency of a smooth transition between the two administrations particularly during the COVID-19 pandemic, which he compared to a war.

"We're in the middle of a war, and we don't know who the generals are going to be. We don't know what the game plan is," he said. "We can't wait till the end of January."

Amid the president's claims of fraud and a stolen election, Hogan dismissed those allegations for lack of evidence and asserted that even if there were any issues, like any other election, it will not make up Trump's deficit against Biden.

"We're not going to make up for five million votes in all of those states. It was a pretty overwhelming victory," Hogan continued. "We ought to find out if there's anything wrong but so far we haven't heard anything."
