White House staff have been ordered to wear a mask or facial covering to enter the West Wing, as Donald Trump confronts cases of the coronavirus at the heart of his administration.
Two known cases of Covid-19 among employees in one of the most-protected complexes in America have sent three of the nation's top medical experts into quarantine and vice president Mike Pence into self-isolation.
The scare comes as the White House this week emphasise to the American people the steps being taken to assure their safety - in hopes that will coax them to resume normal activities.
Staff will be allowed to remove face coverings if they sit at least six feet apart from colleagues. Mr Trump himself is still not expected to wear a mask.
