Archbishop Carlo Maria Viganò, a former Vatican diplomat in Washington, alleges in a letter published Sunday that Pope Francis knew about the sexual abuse committed by a top American clergyman years before he was publicly disgraced.

The allegations come just days after Francis denounced the Church’s history of abuse in a letter to all Catholics.
