While exiting evening Mass at St. Ann's Catholic Church in Wilmington, Delaware, on Saturday, Biden responded to a shouted question from a member of the press pool by saying that all Americans should be able to attend religious service "safely" during the ongoing pandemic.

"Mr. Biden, should all Americans, sir, be able to attend religious services during the pandemic?" a reporter asked Biden.

"Yes, safely," the president-elect responded.

Biden did not respond to a follow-up question on whether that means all Americans should be able to attend indoor religious services like he is able to.

The president-elect has consistently attended indoor church services near his Delaware home since the summer, usually with family and always wearing a mask.

However, it may become more difficult to do so when Gov. John Carney's new coronavirus restrictions take effect on Monday. They will limit indoor gatherings outside of the home to 30% of a venue's capacity and no more than 50 people. Gatherings inside the home will be limited to no more than 10 people, and outdoor gatherings are capped at 50 people but can be expanded to as many as 250 people with approval from the public health department.

As Trump serves out his last few months as president and Biden focuses on the raging coronavirus pandemic during his transition, Trump appeared to have skipped a side-event at Saturday's virtual G20 summit on “Pandemic Preparedness and Response.”

During the time the event was scheduled on the G20 agenda, Trump was at his Virginia golf course. He has since returned to the White House.

French President Emanuel Macron and German Chancellor Angela Merkel were among the speakers at the event.

Trump’s brief participation in the virtual summit Saturday appears to have been more-or-less limited to the opening remarks. At times during the Zoom style video recording, the president could be seen looking down at something in front of him.

Meanwhile, despite Trump's roadblocks and his administration refusing to recognize Biden as the president-elect -- including not giving him access to pandemic-related information -- Biden is forging ahead and was meeting with transition advisers on Saturday as he prepares to announce key Cabinet positions.

The White House has yet to release a readout of Trump's participation in the summit, but White House Press Secretary Kayleigh McEnany said the president addressed the pandemic in his remarks to world leaders. According to her statement, the president stressed the economic components of the pandemic but also talked about advances in treatments and toward a vaccine.

Rep. Alexandria Ocasio-Cortez became an undisputed congressional star after her 2018 primary upset win followed by her championing of the an ambitious legislative package to address climate change quickly dismissed by Republicans and Democrats alike.

AOC, the unofficial leader of the so-called Squad, has reinforcements in the coming next session of Congress, with Reps.-elect Jamaal Bowman, Mondaire Jones and Cori Bush joining the push to address climate change – complicating Joe Biden’s presidency before it even begins.

In a preview, she and the rest of the Squad rallied outside the DNC headquarters on Thursday – firing the first shots of the intraparty civil war as they demanded the Biden deliver on his campaign pledge to enact climate justice – despite pressure from corporate lobbyists.

Ocasio-Cortez claims she’s secured a commitment from the president-elect on a $2 trillion climate plan – which may be more than Biden can deliver given the political divide on Capitol Hill.

A month ago, Biden said that he does not support the Green New Deal, though he has laid out his own plan for addressing climate change.

The Trump campaign released a statement Sunday night distancing itself from attorney Sidney Powell, saying she's not a member of the "Trump Legal Team," despite President Trump previously announcing that she was.

"Sidney Powell is practicing law on her own. She is not a member of the Trump Legal Team. She is also not a lawyer for the President in his personal capacity," Trump campaign attorneys Rudy Giuliani and Jenna Ellis said in a statement.

The statement comes after Powell advanced a series of unproven election claims in an interview on Newsmax and at a recent press conference on behalf of the campaign, portions of which were retweeted by the official GOP Twitter account.

The president last week announced Powell as a member of his legal team along with Giuliani, Ellis, and attorneys Joseph diGenova and Victoria Toensing.
