The Archbishop of Boston has said that he has asked the rector of the main archdiocesan St John Seminary to go on sabbatical leave immediately and is asking for an investigation of allegations made on social media about activities there "directly contrary to the moral standards and requirements of formation for the Catholic priesthood."

"At this time, I am not able to verify or disprove these allegations," said Boston Cardinal Sean O'Malley in a statement sent to media via email. He does not say in the statement what the allegations are about.
