President Trump‘s physician released details about the commander-in-chief’s medical condition and treatment Friday, following the bombshell announcement hours earlier that the first couple had been stricken with COVID-19.

On Friday afternoon, Dr. Sean P. Conley, the president’s physician, released an update on the president’s condition.

“Following PCR-confirmation of the President’s diagnosis, as a precautionary measure he received a single 8-gram dose of Regeneron’s polyclonal antibody cocktail,” a memo released Friday afternoon by Dr. Sean P. Conley, the president’s physician, stated. “He completed the infusion without incident.”

“In addition tot he polyclonal antibodies, the President has been taking zinc, Vitamin D, famotidine, melatonin and a daily aspirin,” Conley said.

Conley added that “as of this afternoon, the President remains fatigued but in good spirts.”

“He’s being evaluated by a team of experts, and together we’ll be making recommendations to the President and First Lady in regards to next best steps,” Conley said.

Conley added that the first lady “remains well with only a mild cough and headache, and the remainder of the First Family are well and tested negative for SARS-CoV-2 today.”

White House chief of staff Mark Meadows told reporters at the White House Friday that the president and first lady “remain in good spirits.”

“The president does have mild symptoms, and as we look to try to make sure that not only his health and safety and welfare is good, we continue to look at that for all of the American people,” Meadows continued, adding that he is not only “in good spirits, but very energetic.”

Meadows, though, did not elaborate on the types of symptoms the president was experiencing, or any potential treatments the president’s medical team was reviewing.

The first lady, on Friday, tweeted, thanking for “the love you are sending our way,” while confirming she, too, is experiencing symptoms.

“I have mild symptoms but overall feeling good,” the first lady tweeted. “I am looking forward to a speedy recovery.”

The president announced his positive COVID-19 test results just before 1:00 a.m. Friday.

“Tonight, @FLOTUS and I tested positive for COVID-19,” the president tweeted. “We will begin our quarantine and recovery process immediately.”

He added: “We will get through this TOGETHER!”

Conley, the president’s physician, also confirmed Trump and the first lady’s positive COVID-19 tests.

“This evening I received confirmation that both President Trump and First Lady Melania Trump have tested positive for the SARS-coV-2- virus,” Conley said. “The President and First Lady are both well at this time, and they plan to remain at home within the White House during their convalescence.”

“The White House medical team and I will maintain a vigilant watch, and I appreciate the support provided by some of our country’s greatest medical professionals and institutions,” he continued.

He added: “Rest assured I expected the President to continue carrying out his duties without disruption while recovering, and I will keep you updated on any future developments.”

Friday morning Democratic presidential nominee Joe Biden said that he and his wife Dr. Jill Biden tested negative for COVID-19.

“I’m happy to report that Jill and I have tested negative for COVID,” Biden tweeted. “Thank you to everyone for your messages of concern. I hope this serves as a reminder: wear a mask, keep social distance, and wash your hands.”

Biden’s primary care physician, Dr. Kevin O’Connor, issued a statement Friday saying: “Vice President Joe Biden and Dr. Jill Biden underwent PCR testing for COVID-19 today and COVID-19 was not detected.”

“I am reporting this out in my capacity as both Vice President Biden and Dr. Biden’s primary care physician,” O’Connor said.

Biden addressed Trump’s diagnosis early Friday, offering prayers for a speedy recovery.

“Jill and I send our thoughts to President Trump and First Lady Melania Trump for a swift recovery. We will continue to pray for the health and safety of the president and his family,” Biden said.

There’s no word yet on when the former vice president was last tested for the coronavirus — or when he’ll next be tested. But the campaign told Fox News that Biden’s running mate, California Sen. Kamala Harris, was tested Thursday, as part of the campaign’s routine testing, and tested negative.

House Speaker Nancy Pelosi, D-Calif., said she is praying for the president, but that she hopes he will now take “a saner approach” to the coronavirus after being diagnosed.

“We all received that news with great sadness. I always pray for the president and his family that they are safe, continue to do so more intensified, and I know that he’ll have the best of care, and that’s what we want for everyone in our country,” Pelosi said on MSNBC Friday morning. “I hope this will be a moment where people will understand that what we have in our HEROES bill and what we have over and over is we must have testing, tracing, treatment. We must have spacial distancing. We must be wearing our masks.”

She added: “So maybe now that people who see the president of the united states with all the protection that he has and the first lady still having this exposure, it might be as you say a learning experience…. This is tragic, it’s very sad. … Going into crowds unmasked and all the rest is sort of a brazen invitation for this to happen. Sad that it did, but nonetheless hopeful that it will be a transition to a saner approach to what this virus is all about.”

Meanwhile, Vice President Mike Pence early Friday offered prayers for the president and first lady. A spokesman said Pence and his wife tested negative Friday morning.

“Karen and I send our love and prayers to our dear friends President @realDonaldTrump and @FLOTUS Melania Trump,” Pence tweeted. “We join millions across America praying for their full and swift recovery. God bless you President Trump & our wonderful First Lady Melania.”

A White House official told Fox News on Friday that most West Wing officials and staff who are in close proximity to the president are tested for COVID-19 daily.

Another White House official told Fox News that White House Chief of Staff Mark Meadows tested negative for COVID-19 in his most recent test. That test, according to the official, was conducted as part of normal protocol.

Meanwhile, Supreme Court nominee Judge Amy Coney Barrett, who has met with 32 senators on Capitol Hill this week as she prepares for Senate Judiciary Committee hearings set to begin on Oct. 12, has tested negative for the coronavirus as well, according to the White House. The White House says that she last had contact with Trump on Saturday when he announced her Supreme Court nomination.

The president and first lady’s positive coronavirus tests came just hours after news surfaced that senior White House adviser Hope Hicks tested positive for COVID-19.

Trump participated in the first presidential debate against Biden on Tuesday, before he or Hicks began showing symptoms or tested positive for the virus.

According to a source familiar, Hicks — who has been traveling with the president this week — began showing symptoms of coronavirus Wednesday night, either during or after Trump’s Duluth campaign event. She was quarantined aboard Air Force One on the way back and tested positive on Thursday morning, the source said.

The fact Hicks tested positive on Thursday morning means that her diagnosis was known to the White House when Trump went to Bedminster, N.J., on Thursday.

“Hope Hicks, who has been working so hard without even taking a small break, has just tested positive for Covid 19,” Trump tweeted late Thursday. “Terrible! The First Lady and I are waiting for our test results. In the meantime, we will begin our quarantine process!”

In a statement, White House spokesman Judd Deere said the president “takes the health and safety of himself and everyone who works in support of him and the American people very seriously.”

“White House Operations collaborates with the Physician to the President and the White House Military Office to ensure all plans and procedures incorporate current CDC guidelines and best practices for limiting COVID-19 exposure to the greatest extent possible both on complex and when the President is traveling,” Deere said.

White House Press Secretary Kayleigh McEnany tweeted that “the strength of the entire country is with President @realDonaldTrump and @FLOTUS.”

“America stands united. Our country stands strong,” McEnany tweeted. “Your President will continue to put the People first!”

But national security sources tell Fox News that the president should be planning to delegate his authority should his symptoms become severe and his situation become extreme, citing continuity of government provisions in the 25th Amendment of the U.S. Constitution.

“Whenever the President transmit to the President pro tempore of the Senate and the Speaker of the House of Representatives his written declaration that he is unable to discharge the powers and duties of his office, and until he transmits to them a written declaration to the contrary, such powers and duties shall be discharged by the Vice President as Acting President,” the 25th Amendment reads.

Sources told Fox News that the internal White House group, called the “Continuity of Government Operations Team,” is currently working to prevent a mass outbreak of the coronavirus among White House staff and relocate staff to multiple locations to contain exposure.

A former senior intelligence official also said that Trump or Pence should address the nation on Friday to send a signal that the U.S. government will continue to function. A White House official, however, says that there are not plans as of Friday morning for a national address.

Meanwhile, officials around the globe offered their prayers to the president and first lady, including World Health Organization (WHO) Director-General Tedros Adhanom Ghebreyesus.

“My best wishes to President @realDonaldTrump and @FLOTUS for a full and speedy recovery,” he tweeted on Friday morning.

Chancellor Angela Merkel also sent her best wishes to the president and first lady, according to a tweet by Steffen Seibert, a government spokesman for Germany.
