Updated 12:50 PM ET, Mon June 14, 2021
Britain's Queen Elizabeth II welcomed US President Joe Biden to Windsor Castle on Sunday, June 13.
It was her first one-on-one engagement with a world leader since the start of the Covid-19 pandemic. And it's among her first public engagements since her husband, Prince Philip, died in April.
Since the Queen ascended to the throne in 1952, there have been 14 US presidents. She has met with all of them except for Lyndon B. Johnson.
