President Donald Trump’s national security adviser, Robert O’Brien, has tested positive for coronavirus, the White House has confirmed.
Mr O’Brien, 54, has been self-isolating and working from home.
The aide has mild symptoms and there was no risk of exposure to Mr Trump or Vice-President Mike Pence, a statement said.
