In a 2025 Us cover story, Mary shared that she was "shocked" when she learned about Robert Jr.'s battle. "I immediately started blaming myself, because I thought, 'You can't judge him and his life and his choices,'" she said at the time. "I don't believe in judging people. I'm just not a judger. I don't like judging people, and I don't like to do it. ... If he's opening up enough to tell me something this crucial, then why would I judge? I have no choice but to sit there and receive it and accept it and hope that I can help him." While Mary shared that her son "had a little bit of a setback" in his recovery at the time, she prayed that he "stays good," adding, "I can honestly sit here and say he's doing very good."
