Vatican City, Apr 29, 2016 / 09:35 am (CNA/EWTN News).- U.S. Vice President Joe Biden went to the Vatican for a summit on regenerative medicine, where he offered praise to Pope Francis and advocated for a global push to cure cancer.

Biden opened his speech by recalling how while visiting the U.S. last September, Pope Francis had comforted him for the loss of his eldest son Beau, who passed away last summer at the age of 46 from brain cancer.
