Joe Biden has spent these early days as President-elect pleading with Americans to pay attention to the relentless surge of Covid-19 – with deaths averaging more than 1,000 a day in the past week – as President Donald Trump continues to ignore the deepening crisis and touts the promises of yet-to-be-approved vaccines as his panacea. The continuing power struggle between two men with diametrically different philosophies on how the US should handle the virus has left the nation rudderless at this critical moment – forced by Trump into a governing crisis as he refuses to let the transition to the Biden presidency proceed and pass on knowledge that could be critical to slowing the spread of the virus next year. This past week, some Republicans in Congress finally seemed to take note of how the President’s blockade was threatening national security – as Republican Sens. James Lankford of Oklahoma, Chuck Grassley of Iowa and Senate Majority Whip John Thune of South Dakota, among others, stepped up to say that the President-elect should begin receiving intelligence briefings as is customary during the transition of power. But there is no indication that top GOP leaders are applying that same logic to the deadly increase in coronavirus cases, even though the number of patients in US hospitals hit an all time pandemic high last week, according to data from the Covid Tracking Project. As of Saturday, more than 69,000 Americans were hospitalized, according to the organization’s tallies. Many of the country’s top medical experts are underscoring the importance of a functioning transition, including Dr. Anthony Fauci, the nation’s top infectious disease specialist, who has served six presidents over four decades. “It’s very clear that that transition process that we go through, that time period measured in several weeks to months, is really important in a smooth handing over of the information,” Fauci told CNN’s Jake Tapper Sunday on “State of the Union.” “It’s almost like passing a baton in a race – you don’t want to stop and then give it to somebody. You want to just essentially keep going. And that is what transition is. So, it certainly would make things more smoothly if we could do that.” When asked about projections that another 200,000 deaths are possible in the next four months, Fauci said the country can change that trajectory by “very, very vigorously adhering to the public health measures” in combination with swift distribution of a vaccine. “We don’t have to accept those large numbers that are so terrifying,” he said. But the President is still adhering to the same hands-off approach that led so many voters to reject his leadership on Election Day, inaccurately stating that the increase in cases is the result of increased testing as he tries to focus public attention on his administration’s efforts to speed up a vaccine through Operation Warp Speed. Adm. Brett Giroir, the Covid-19 testing coordinator for the Department of Health and Human Services and a member of the White House coronavirus task force, confirmed Sunday on ABC’s “This Week” that it has been five months since Trump attended a task force meeting. He called the news about a potential vaccine that is 90% effective “a game changer” but warned of the dangers of the nation’s current predicament. “We really are in a critical situation today, with over 180,000 cases yesterday, hospitalizations up, mortality up,” Giroir told ABC’s Martha Raddatz Sunday. Trump’s focus however is still on the election results. For the first time Sunday morning acknowledged Biden’s election victory, tweeting, “He won because the Election was Rigged,” before continuing to blame his loss on baseless and debunked conspiracy theories about the election. In another tweet shortly after, he stood by his false belief that he may be able to win the election, saying: “I concede NOTHING! We have a long way to go.” The President spent most of Saturday golfing and tweeting similar false conspiracy theories, and driving by a crowd of his supporters who gathered in Washington to protest the election results on the basis of his lies and propaganda. He barely addressed the virus on Twitter Saturday, tweeting: “Congress must now do a Covid Relief Bill. Needs Democrats support. Make it big and focused. Get it done!” Amid that leadership vacuum, many doctors and top medical experts are bracing for even greater holiday spikes, noting that Americans have simply let their guards down and given in to the desire to return to normal life. The President unquestionably played a role in those attitudes as the administration abandoned its public coronavirus task force briefings months ago and he tried to win reelection by advancing the falsehood that the US was “rounding the corner.” RELATED: Live results from CNN’s Election Center Given the complexities of rapid vaccine distribution and the potential for catastrophic consequences if doctors, hospitals and first responders don’t have what they need to handle the current rise in Covid-19 cases, Democrats – and even some Republicans from past administrations – are sounding the alarm about the need for more communication between the outgoing and incoming administrations in this moment of national crisis. “It’s a very grave situation,” Incoming White House chief of staff Ron Klain told NBC’s Chuck Todd on “Meet the Press.” “He’s not the president now; there’s not that much that Joe Biden can do right now to change things, other than to reiterate kind of message you heard from (infectious disease expert) Dr. (Michael) Osterholm, which is that all Americans and our state and local governments need to step up right now,” said Klain, noting that Biden, as president, will institute a national mask mandate. “If the President, the administration is not going to lead, that’s where the leadership has to come from,” Klain added. “That will change on January 20 but right now we have a crisis that’s getting worse.” Lack of communication raises alarm about virus response Trump is blocking any meaningful exchange of coronavirus information – beginning with the refusal of his appointee at the General Services Administration to ascertain the election, the first step that would allow the flow of transition funds and streamlined background checks for incoming staff. That’s forced the Biden team to get up to speed on the pandemic response by back-channeling with governors, members of the private sector and the medical community as they try to shape the nation’s coronavirus response plan for next year. While Biden is publicly projecting calm about the governing crisis — allowing the Trump campaign’s election challenges to work their way through the courts, where they are amassing a growing string of defeats — he called for “urgent action” Friday by the Trump administration, including an acknowledgment of how serious the current Covid-19 situation is. “This crisis demands a robust and immediate federal response, which has been woefully lacking. I am the president-elect, but I will not be president until next year,” Biden said, underscoring the limitations of his position. “The crisis does not respect dates on the calendar, it is accelerating right now.” The President-elect’s advisers have been increasingly vocal about their concerns about the lack of information sharing between the current and future administrations. “This is truly a national security threat,” Dr. Celine Gounder, an infectious diseases specialist, epidemiologist and Biden Transition Covid-19 board member, said on CNN’s “Anderson Cooper 360” Friday evening. “I cannot even imagine another situation — if we were in the midst of a war — that you wouldn’t have handoff of information and plans to a succeeding president.” As the US smashed through another set of coronavirus records on Friday evening, Dr. Vivek Murthy, co-chair of Biden’s transition coronavirus advisory board, told Blitzer it was “a grim day for the country.” “We’re at a point now, even pre-Thanksgiving, where we are surging beyond any level that we have seen over the last eight months,” Murthy, a former surgeon general under President Barack Obama, said on “The Situation Room.” “What we do over these next few weeks is going to have a profound impact on whether this spread increases or whether we ultimately control the spread of this virus.” Fauci acknowledged Sunday that that alarming increase in cases, hospitalizations and deaths could prompt more leaders to reinstate local or statewide stay-at-home orders. He said he expects governors and mayors to start looking at “very surgical-type of restrictions, which are the function equivalent of a local lockdown.” “But we’re not going to have a national lockdown,” he added. Local leaders weigh stronger measures to curb the virus In the absence of a vigorous federal response to slow the spread of the virus, there are signs that local leaders are once again considering more dramatic action to control the spread, which could create economic and logistical disruptions. The 2.4% test positivity rate in New York City is now close enough to the 3% threshold that could lead the city to close schools and transition students to remote learning, a possibility that New York Gov. Andrew Cuomo discussed during a call with journalists Saturday where he added that some schools might be able to “test out” of closures if they have a much lower positivity rate than the surrounding area. The resurgence in Oregon, where cases topped more than 1,000 a day for the third day in a row Saturday, led Gov. Kate Brown to announce a “two week freeze” on Friday that will limit social gatherings to six people and two households, close restaurants and bars and place new limits on the number of people who can gather within faith-based organizations. The freeze will span from November 18 to December 2. “I know it’s hard and I know everybody is weary but we are trying to stop this ferocious virus from spreading,” Brown said. On Saturday, the Navajo Nation ordered a new three-week stay-at-home lockdown, restricting travel and only allowing residents to leave their homes for emergencies or to pick up groceries, medicine and firewood. “We are inching closer and closer to a major public health crisis in which we could potentially see our hospitals filling up with patients,” Navajo Nation President Jonathan Nez said in a statement. “Our health care system on the Navajo Nation cannot sustain a long-term surge in Covid-19 cases. The safest place to be is at home.” This story has been updated with additional developments Sunday.
