Trump campaign distances itself from attorney Sidney Powell: Transition updates

Biden, forging ahead with his transition despite Trump's refusals to concede, has named new members of his senior White House staff, bringing several of his closest campaign advisers into the fold. 

“I am proud to announce additional members of my senior team who will help us build back better than before," Biden said in a release Monday. "America faces great challenges, and they bring diverse perspectives and a shared commitment to tackling these challenges and emerging on the other side a stronger, more united nation."

Biden announced the following:

• Mike Donilon, senior adviser to the president
• Jen O’Malley Dillon, deputy chief of staff 
• Dana Remus, counsel to the president 
• Steve Ricchetti, counselor to the president
• Cedric Richmond, senior adviser to the president and director of the White House Office of Public Engagement 
• Julie Rodriguez, director of the White House Office of Intergovernmental Affairs 
• Annie Tomasini, director of Oval Office Operations 

While the former vice president has touted he pledged to build a diverse administration, five of the seven staffers are white, though women outnumber the men on the list. Notably missing from the list are any communication staffing announcements.

Also on the list are some members of Jill Biden’s staff, who worked with her during the campaign:

• Anthony Bernal, senior adviser to Jill Biden
• Julissa Reynoso Pantaleon, chief of staff to Jill Biden

While Biden forges ahead and continues to build out his White House team, he remains hindered by the lack of a formal concession from Trump.

The Trump administration is still not recognizing Biden as the president-elect, and Biden warned Monday "more people may die" without a the process of a formal transition as the country battles the coronavirus pandemic on top of ongoing national security concerns. 

Taking matters into his own hands, Biden and Vice President-elect Kamala Harris will receive a briefing on national security from security and defense advisers in Wilmington, Delaware, on Tuesday, as they stress their work must begin now and not on Jan. 20. 

The briefing comes as Trump makes [geo-political moves not typical of a lame-duck commander-in-chief. Two officials confirmed to ABC News on Monday that orders were expected by the end of this week to reduce troop levels in Afghanistan to 2,500 and in Iraq to 2,500 by mid-January.

Notably, Biden has said Harris is still getting briefings based on her role on the Senate Intelligence Committee, but it’s unclear how much she can pass on to Biden.

Pressing forward, Biden is also expected to name a number of senior White House staff as soon as this week, a group that will likely include Rep. Cedric Richmond, D-La., a key surrogate and his campaign's first national co-chair. Biden's campaign manager Jen O'Malley Dillon is expected to join the administration as deputy chief of staff, sources confirmed to ABC News.

While Trump has no public events on his schedule for Tuesday, Vice President Mike Pence will lead a coronavirus task force meeting at the White House as the administration faces criticism on Trump’s apparent lack of interest in managing the virus. Trump hasn’t attended a task force meeting for months.

It all comes as state certification deadlines approach for the 2020 election, and the Trump campaign, working against those deadlines, also fights against the results which voted him out of office.

Biden is making clear that he wants Trump's help with the transition -- and is even warning that lives could be lost if he doesn't get it.

But Biden is signaling that he doesn't truly expect that help. He is acting in ways that say he doesn't really need it, much as it might boost his incoming presidency -- and maybe help the health of the nation.

The former vice president is outlining an agenda that actually starts before Jan. 20, with more stimulus spending now and mask mandates designed to slow the spread of COVID-19. He is setting up task forces and working groups along with a revamped West Wing staffing operation designed to adapt to the particular challenges of the moment.

"It would make it a lot easier," Biden said Monday, "if the president were to participate."

Biden remains among the more calm Democrats in official circles. He's letting his surrogates and lawyers do battle with sputtering legal efforts and a torrent of falsehoods about the election propagated by the president.

It's appropriate to ask Republican members of Congress to say that Trump should acknowledge the facts and help assure smooth governance. Democrats, of course, have strong opinions on the subject as well.

What's becoming clear, though, is that state authorities and ultimately the judicial branch will be forced to end scattered election disputes. Trump will still be president when that happens; in some states, finality might be just days away.

But by then, Biden's plan is to be well on his way to doing a job Trump isn't showing particular interest in at the moment.

The top General Services Administration official who's blocking Biden's transition team from accessing government resources ahead of his inauguration appears to be looking for a new job, according to a message obtained by ABC News.

Emily Murphy, head of the GSA who was appointed by Trump in 2017, recently sent that message to an associate inquiring about employment opportunities in 2021, a move that some in Washington interpreted as at least tacitly acknowledging that the current administration soon will be gone.

Murphy has the power to decide -- or "ascertain" -- when election results are evident enough to trigger a transition of power, allowing the winning team access to career staff at federal agencies and internal government information including national security matters and plans for administering a COVID-19 vaccine. She's so far refused to certify Biden as the election's winner as Trump attempts to overturn the election result in court.

A GSA spokesperson denied the account that Murphy was actively looking for a job, but noted that it wouldn't be unusual for someone in government, especially a political appointee, to consider future opportunities.

"The administrator remains focused on doing her job," the spokesperson added.
