Here is a snippet from the National Catholic Register:

I regret that in my defense of Father Maciel I took to task Gerald Renner and Jason Berry, the writers who broke the story, and their editors at the Hartford Courant. They didn’t get everything about the Legion right but they were fundamentally correct about Father Maciel’s sexual abuse and I ask forgiveness — too late for Gerald Renner, who is deceased.
To Father Maciel’s victims, I pray you can accept these words: I’m sorry for what our founder did to you. I’m sorry for adding to your burden with my own defense of him and my accusations against you. I’m sorry for being unable to believe you earlier. I’m sorry this apology has taken so long.
