Vigano made the claims in a lengthy statement that concludes with a call for Francis’ resignation: “In this extremely dramatic moment for the universal Church, he must acknowledge his mistakes and, in keeping with the proclaimed principle of zero tolerance, Pope Francis must be the first to set a good example to Cardinals and Bishops who covered up McCarrick’s abuses and resign along with all of them,” he writes.

Vigano, who retired in 2016 at age 75, described an exchange with Francis on June 23, 2013, shortly after he became pope, about Cardinal Theodore McCarrick, the former archbishop of Washington, D.C., who resigned last month over claims he sexually abused seminary students and an altar boy.

Vigano writes that he told Francis about the allegations: “Holy Father, I don’t know if you know Cardinal McCarrick, but if you ask the Congregation for Bishops there is a dossier this thick about him. He corrupted generations of seminarians and priests and Pope Benedict ordered him to withdraw to a life of prayer and penance.”
