"We will begin our quarantine and recovery process immediately. We will get through this TOGETHER!"

White House incumbent Physician to the President, Dr Sean Conley confirmed the news in a memorandum early Friday.

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

The first lady also tweeted early Friday morning, confirming the news.

"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," Melania Trump tweeted.

The news comes just four hours after it was revealed that one of the president's closest advisers, Hope Hicks, had tested positive.

Hicks had travelled with him to Ohio for the debate on Tuesday and to Minnesota for a rally on Wednesday.

Hicks was also on Marine One, the president's helicopter when it left the White House to fly to Joint Base Andrews on Wednesday. She was seen walking to the helicopter with fellow top presidential advisers, such as Stephen Miller, Dan Scavino and Jared Kushner. None of them was wearing masks.

Sources told ABC News that Hicks is experiencing symptoms and that she tested positive on Wednesday.

Trump was on the debate state Tuesday night in Cleveland with Democratic presidential nominee former Vice President Joe Biden.

It was at the first presidential debate where Trump mocked Biden for wearing masks. "I don't wear masks like him. Every time you see him, he's got a mask," he said Tuesday. "He could be speaking 200 feet away and he shows up with the biggest mask I've ever seen."

The Biden campaign has yet to put out a public statement about the positive test result and it's unknown how Trump's diagnosis will impact the second debate and next week's vice president debate between Mike Pence and Sen. Kamala Harris.

Pence sent his thoughts to the Trump family Friday, saying he's praying for their recovery.

"Karen and I send our love and prayers to our dear friends President @realDonaldTrump and @FLOTUS Melania Trump. We join millions across America praying for their full and swift recovery. God bless you President Trump & our wonderful First Lady Melania," Pence tweeted.In light of Trump's positive coronavirus test, the president has canceled Friday's rally. His only scheduled event is a closed press call on COVID-19 support to “vulnerable seniors.”
