WASHINGTON (Reuters) - On the morning of Jan. 20, hours before Joe Biden arrived at the White House as the 46th U.S. president, a clear plexiglass shield was erected at the guard's desk at the entrance to the West Wing housing the executive offices.

It was a small but noticeable sign that things were changing: COVID-19 protections missing during Donald Trump's last year in office would be a regular part of White House life in the Biden administration.
