Embedded Player There's a nun in Texas that is known for being one of the nation's strongest champions for immigrants: Sister Norma Pimentel. Sister Norma is currently the executive director of the Catholic Charities of the Rio Grande Valley, but growing up, she wanted to be an architect. However, a chance encounter with pizza, of all things, changed her life forever. Maria Hinojosa visits Sister Norma in her convent chapel to talk about running the Humanitarian Respite Center in McAllen, Texas, and the work she is doing in her border community for immigrants.
