NEW YORK (WCBS 880) -- President Donald Trump and First Lady Melania Trump have tested positive for COVID-19, the president announced on Twitter early Friday morning.
According to CBS News, the president looked unusually rundown upon his return to the White House on Thursday after attending a fundraiser at his New Jersey golf club.
Hours later, he confirmed his diagnosis.
“Tonight, @FLOTUS and I tested positive for COVID-19. We will begin our quarantine and recovery process immediately. We will get through this TOGETHER!” the president tweeted just before 1 a.m.
The first lady followed suit, tweeting, "As too many Americans have done this year, @potus & I are quarantining at home after testing positive for COVID-19. We are feeling good & I have postponed all upcoming engagements. Please be sure you are staying safe & we will all get through this together."
Dr. Sean Conley, the physician to the president, said in a memo released by the White House, that the Trumps tested positive for SARS-COv-2. "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," he wrote in the memo.

Trump had been carrying out his duties at the White House while experiencing mild symptoms, including a low-grade fever, but was being admitted to Walter Reed National Military Medical Center as a precaution for a few days.
"President Trump remains in good spirts, has mild symptoms, and has been working throughout the day. Out of an abundance of caution, and at the recommendation of his physician and medical experts, the President will be working from the presidential offices at Walter Reed for the next few days. President Trump appreciates the outpouring of support for both he and the First Lady," Press Secretary Kayleigh McEnany said.
The president is 74 years old, an age where the virus carries a higher risk for severe illness from the virus, according to the CDC. He now joins the other 7.2 million Americans to have tested positive for the virus since the outbreak began.
In an earlier statement, Physician to the President Sean Conley said Trump “remains fatigued but in good spirits” and has “received a single 8 gram dose of Regeneron’s polyclonal antibody cocktail” and “completed the infusion without incident."
President Trump's campaign manager says all campaign events involving the president and his family will either be turned into virtual events or postponed until further notice.
Bill Stepien, who heads Trump's reelection, says Vice President Mike Pence, who has tested negative for COVID-19, plans to continue to his campaign schedule.
The president could be off the campaign trail for at least 10 days as he recovers from coronavirus, CBS News has learned. He had planned extensive travel over the course of the next week, including several stops in the west.
In a tweet Friday afternoon, the First Lady said, "Thank you for the love you are sending our way. I have mild symptoms but overall feeling good. I am looking forward to a speedy recovery."
FLOTUS Chief of Staff Stephanie Grisham confirmed to CBS News that the president's son, 14-year-old Barron, has tested negative.
"All precautions are being taken to ensure he's kept safe and healthy," Grisham said.
Vice President Mike Pence and his wife tested negative for the virus.
"As has been routine for months, Vice President Pence is tested for COVID-19 every day. This morning, Vice President Pence and the Second Lady tested negative for COVID-19. Vice President Pence remains in good health and wishes the Trumps well in their recovery," his press secretary Devin O’Malley tweeted.
Former Vice President Joe Biden said, "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."
The Democratic presidential candidate and his wife were tested for the coronavirus Friday morning after Biden appeared on stage with Trump at Tuesday's presidential debate with Trump.
Trump and Biden did not shake hands during the debate but stood without masks about 10 feet apart for the 90-minute event.
Biden announced that both he and his wife have tested negative for the virus.
"I’m happy to report that Jill and I have tested negative for COVID. 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," he tweeted.
It's not yet clear whether the next debate between Trump and Biden, which was to take place in two weeks, will go ahead as planned.
Just hours before announcing his diagnosis, Trump had told Sean Hannity on Fox News that he and the first lady had been tested and were awaiting the results after Hope Hicks, one of Trump’s closest advisors, tested positive for COVID-19.
"So she did test positive," Trump said of Hicks. "I just heard about this. She tested positive. She's a hard worker. A lot of masks. She wears masks a lot. But she tested positive. I just went out with a test. The first lady also went out with a test. So whether we quarantine or whether we have it, I don't know .... So I just went for a test and we'll see what happens. Who knows."
New York Gov. Andrew Cuomo issued a statement Friday morning saying he wishes President Trump and the First Lady "a full and speedy recovery."
"This virus is vicious and spreads easily. Wear a mask. Let's all look out for each other," Cuomo statement reads.
Meanwhile, New Jersey Gov. Phil Murphy and First Lady Tammy Murphy released a statement sending their “best wishes” to the president and urged everyone who attended Trump's Bedminster fundraiser on Thursday afternoon to “take full precautions, including self quarantining and getting tested.”
