In a Friday phone call, White House chief of staff Mark Meadows suggested to FDA Commissioner Stephen Hahn that his job could be on the line if his agency doesn't authorize emergency use of the Pfizer-BioNTech vaccine by the end of the day, sources familiar with the matter said.

"We don’t comment on private conversations, but the chief regularly requests updates on progress toward a vaccine," a White House official told ABC News.

Vaccine authorization by the FDA is expected imminently, as early as today.

Dr. Anthony Fauci told The New York Times that he'll “get vaccinated publicly, in the public space, so that people can see me getting vaccinated,” as soon as “the vaccine becomes available to me.”

Former Presidents Barack Obama, George Bush and Bill Clinton have all offered to get vaccinated on camera.

The Food and Drug Administration as early as today could authorize emergency use authorization for the Pfizer-BioNTech vaccine.

California reported 35,468 new cases on Friday and 12,940 hospitalizations, both record highs.

Gov. Gavin Newsom has issued stay-at-home orders to regions if their intensive care unit capacity falls below 15%. The San Joaquin Valley, Southern California and the Greater Sacramento region all have fallen below that threshold, while the Bay Area and Northern California have not.

The U.S. has set new records for the most deaths in one week, the highest number of new cases in a week and the most Americans hospitalized in one week, according to ABC News’ analysis of COVID Tracking Project data.

In the past seven days, the U.S. has reported more than 1.4 million COVID-19 cases -- roughly equivalent to 142 Americans testing positive for the virus every minute.

Daily case numbers have been on the rise for nearly three months, increasing nationally by 480% since mid-September.

The U.S. broke a hospitalization record again on Thursday, surpassing 107,000 patients, a 6.5% rise from a week earlier. Fifteen states have reported record numbers since Sunday.

With the U.S. is now averaging over 2,300 new coronavirus related deaths a day, more Americans are dying from COVID-19 every day than ever before.

“We are in the timeframe now that probably for the next 60 to 90 days we're going to have more deaths per day than we had at 9/11 or we had at Pearl Harbor,” Centers for Disease Control and Prevention Director Robert Redfield said Thursday at an event hosted by the Council on Foreign Relations.

In the 9/ll attacks, almost 3,000 Americans died, and more than 2,400 were killed when Japan attacked Pearl Harbor in 1941.

U.S. Surgeon General Jerome Adams urged people to take the coronavirus pandemic seriously and follow public health guidelines as infections and hospitalizations soar across the country.

"I want the American people to know this virus is incredibly unforgiving, cases are going up, hospitalizations are going up, my colleagues are dog-tired and we need you to hang on just a little bit longer because we've got vaccines coming but we want as many people to be alive to get them as possible and a lot of that is going to depend on your behavior," Adams told ABC News chief anchor George Stephanopoulos in an interview Monday on "Good Morning America."

Although "more people than ever are wearing masks," Adams said he's "very" concerned by the number of people who still "don't understand how much spread is occurring by people who don't have symptoms."

About 20 million "full doses" of COVID-19 vaccines will be available by the end of the year, according to Adams, who urged every American to be immunized against the virus as soon as a vaccine is authorized and made available.

"It's a way that we can ultimately end this pandemic, but it doesn't matter if people won't get the vaccination," the surgeon general said. "We know that vaccine levels are only about 50% for adults for flu and they go down to about 40% for African-Americans."

Adams said he is working with historically black colleges and universities as well as faith communities to bolster vaccine confidence among all populations. The White House is also hosting a vaccine summit Tuesday, he said.

"One thing you can all do right now, it's national flu immunization week, get your flu shot because half a million people were hospitalized last year with the flu," Adams said. "We simply can't afford for that to happen this year with hospitals being overwhelmed."

The surgeon general said the current surge in infections across the country "is different than earlier surges," because it's not about a lack of masks or personal protective equipment, nor is it due to a lack of testing.

"It's really about health care capacity, and certain places are just being overwhelmed," he said. "So we know that we can actually help them with their health care capacity by immunizing their health care staff. We're going to leave it up to the states, but we're going to give them guidance."

Adams noted it's also important to vaccinate those who are most likely to die from COVID-19.

"We know that 40 to 50% of the deaths are occurring in people who are in longterm care facilities who are older," he said.
