Pope Francis is sending the Vatican's top expert on sexual abuse to Chile to investigate accusations that a bishop covered up for an abusive priest. The Pope met the priest's victims on a recent visit, but then affirmed his belief that Bishop Juan Barros was innocent, and accused people of slandering him. He later apologised for the comments. Critics have insisted the choice to ordain the bishop should be reviewed, and asked for further action. Investigator Archbishop Charles Scicluna will visit Chile and ‘listen to those who want to submit information in their possession’.
