(CNN)President Donald Trump and first lady Melania Trump tested positive for coronavirus, the President announced early Friday morning, an extraordinary development coming months into a global pandemic and in the final stretch of his reelection campaign.
"Tonight, @FLOTUS and I tested positive for COVID-19. We will begin our quarantine and recovery process immediately. We will get through this TOGETHER!" Trump tweeted shortly before 1 am Friday.
In a memo issued to reporters around 1 a.m. ET, the President's physician, Navy Commander Dr. Sean Conley, wrote he received confirmation of the positive tests on Thursday evening.
"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," Conley wrote.
"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," Conley wrote, without elaborating what assistance was being provided to the White House.
"Rest assured I expect the President to continue carrying out his duties without disruption while recovering, and I will keep you updated on any further developments," he wrote.
The President had said late Thursday night that he planned to quarantine after one of his closest aides tested positive for the infection.
"Hope Hicks, who has been working so hard without even taking a small break, has just tested positive for Covid 19. Terrible! The First Lady and I are waiting for our test results. In the meantime, we will begin our quarantine process!" Trump tweeted Thursday night.
Hicks has traveled with the President multiple times recently, including to the debate in Cleveland on Tuesday, and was seen boarding Marine One, along with several other of the President's closest aides -- Jared Kushner, Dan Scavino and Nicholas Luna -- none of whom wore masks, on Wednesday as Trump was heading to a campaign rally in Minnesota.
"She did test positive, I just heard about this. She tested positive. She's a hard worker. Lot of masks, she wears masks a lot but she tested positive. Then I just went out with a test. I'll see -- you know, because we spent a lot of time -- and the first lady just went out with a test also. So whether we quarantine or whether we have it, I don't know," Trump said during a call-in appearance on Fox News' "Hannity."
He added, "I just went for a test and we'll see what happens, I mean, who knows. ... I spent a lot of time with Hope and so does the first lady, and she's tremendous."
While it's unclear what the President's "quarantine process" will look like, the US Centers for Disease Control and Prevention guidelines state that a 14-day quarantine should take place after the last known exposure to someone who has tested positive for Covid-19. This is because the incubation period for the novel coronavirus can be up to two weeks.
