As you may know, Zenit is operated by the Legionaries. Two articles regarding the recent revelations:
Legionary Superior-General Regarding Founder's Life
"I Ask Forgiveness for All This Suffering"
Father Kearns Regarding Life of Father Maciel
"I Entrust His Soul to God’s Infinite Mercy"
I don't recall seeing anything from Zenit, though, confirming the details that have been printed elsewhere (e.g. The New York Times).
