Biden’s one-on-one meeting with Pope Francis, which started shortly after his arrival, lasted nearly 90 minutes. That's notably longer than the pope's 30-minute conversation with President Donald Trump in 2017 and his approximately 50-minute meeting with President Barack Obama in 2014.
The session was held out of public view, lacking even the TV cameras that typically are allowed in at the top of such meetings.
The Vatican said it canceled the planned live broadcast of the beginning of the meeting because of the coronavirus.
The White House has said the topics the leaders planned to discuss include their shared concerns over the COVID-19 pandemic, the climate crisis, and the poor.
