 And when I look at history and presidential history, I can't think of a time in my lifetime, maybe perhaps prior to my lifetime, but not in my lifetime, where we had a president that was this visibly challenged in the mental health arena. But I want to bring in a presidential historian. He's also an attorney with Shackelford, McKinley, and Norton to talk about this. He's been on the program before. Talmadge Boston is the author.
