As it happened: Wear masks in White House, Trump staff told - BBC News
The directive comes after two members of Trump administration staff tested positive for coronavirus.
The White House has sent a memo to staff directing more aides to wear masks when in the West Wing or avoid President Trump's office altogether if possible.

The memo was obtained by US media moments before Trump is due to deliver remarks from the White House on the role of testing in the effort to reopen the country's economy.

It also comes as three high-ranking members of the White House coronavirus taskforce - including top disease expert Anthony Fauci - are in self-isolation after two White House staff members tested positive.

According to US media, the latest White House memo on masks is unlikely to apply to Trump, who has so far not worn one during the pandemic.

Our colleague Anthony Zurcher is at the White House, where he says the number of Trump aides wearing masks has already risen since last week.

He says all of the press aides are donning masks for Trump's briefing.
