U.S. presidents mourned the death of Pope Francis, who served as the leader of the Catholic Church for 12 years, on Monday following the Vatican's announcement of the pope's passing. Pope Francis, who was hospitalized in February due to complications stemming from bronchitis and pneumonia, died Monday at the Vatican's Casa Santa Marta. Here's a look at Pope Francis' legacy with other U.S. leaders: Pope Francis met with former President Barack Obama at the Vatican in March 2014. Trump met with Pope Francis in 2017 during a trip to the Vatican, and told reporters later that they had a 'fantastic meeting.' Former President Joe Biden, the second Catholic U.S. president, visited the Vatican in October 2021, where he and Pope Francis met to discuss topics including climate change and advocacy for the poor, according to a readout of the meeting.
