NSA Robert O’Brien, key Trump adviser has tested positive for coronavirus

President Donald Trump’s national security adviser, Robert O’Brien, has tested positive for coronavirus, the White House confirmed.

Mr O’Brien, 54, has been self-isolating and working from home.

He was picked to replace John Bolton as national security adviser last September, after Mr Bolton left amid a rancorous fallout with President Trump.

The aide has mild symptoms and there was no risk of exposure to Mr Trump or Vice-President Mike Pence, a statement said.

Mr O’Brien is the highest-ranking official in Mr Trump’s administration known to have tested positive.

It is not clear when he and the president last met, but they appeared together two weeks ago on a trip to Miami.

“He has mild symptoms and has been self-isolating and working from a secure location off site. There is no risk of exposure to the president or the vice-president. The work of the National Security Council continues uninterrupted,” the White House statement read.

Anyone near the president is tested regularly for Covid-19.

A number of people in and around the administration have tested positive, including a military member who works as a White House valet, Mr Pence’s press secretary Katie Miller, and a helicopter squadron Marine.
