Hollywood publicist Howard Bragman told People magazine he's known about Sheen's condition for months. "The interview could open up a lot of sympathy for him, but he has to be concerned about a fear of litigation from former sexual partners," he told People.

Bragman later told CNN: "I feel very sorry for his pain. And I hope it's used as a teachable moment for the world. This is a disease that can affect anyone."
