US President Donald Trump and the first lady Melania will go under quarantine after his top aide Hope Hicks tested positive for the coronavirus (Covid-19) disease on Friday.

Both Donald and Melania Trump's  samples have also been taken for the Covid-19 tests. The results are awaited.

Hicks is one of the closest aide to President and serves as the counselor. She has been touring with the Trump for rallies ahead of presidential polls.

Hicks travelled with the president multiple times this week, including aboard Marine One, the presidential helicopter, to a rally in Minnesota Wednesday, and aboard Air Force One to Tuesday night's first presidential debate.

Before Hicks, several other White House staffers have also tested positive for the deadly virus, including Katie Miller, Vice President Mike Pence's press secretary, national security adviser Robert O'Brien, and one of the president's personal valets.
