US President Joe Biden broke down in tears on his visit to Ireland, where he met a priest who gave the last rites to his late son Beau Biden at the Knock shrines. Biden was not on the official guest list, but security gave him clearance to attend the meeting. Biden lit a candle, said a prayer and spent several minutes in private reflection. Later, Biden visited a local hospice and is expected to tour a genealogy centre to know more about his ancestry in Ireland.
