WASHINGTON (Reuters) - The White House has directed staff working in the West Wing, where the daily operations of President Donald Trump’s administration are carried out, to wear masks except when they are at their own desks, two senior administration officials said on Monday. With Trump’s valet and Vice President Mike Pence’s press secretary both testing positive for the deadly coronavirus last week, pressure is growing for the White House to take further steps in protecting the health of the 73-year-old president.
