Rosalynn Carter was an extraordinary champion for the world's poorest, especially women and children. I'll never forget the time I got to spend with her and President Carter at their home in 2017. She told me about a recent trip they had taken to help build 150 new homes for low-income families through Habitat for Humanity. The story was classic Rosalynn: selfless, warmhearted, and accomplishing something that would be impressive at any age. My thoughts are with the entire Carter family today.
