Biden expected to attend Pope Francis' funeral, sources say

Former President Joe Biden, who maintained a close working and personal relationship with Pope Francis dating back to the late pontiff's visit to the United States in 2015, is expected to attend the papal funeral on Saturday in Vatican City, according to multiple people with knowledge of his plans. 

Though final details are still not yet set, Biden does intend to attend, the people said.

Francis began his papacy in 2013 during the Obama administration, but former President Barack Obama is not planning to attend, according to a spokesman.
