Efrén C. Olivares is a human rights lawyer – and he tells Here & Now's Deepa Fernandes that some of the toughest conversations he's ever had were during Trump-era family separations, when he had to tell the parents he was representing in South Texas that he wasn't sure when or where they'd see their children again. His new book, My Boy Will Die of Sorrow, is a firsthand account of the human impacts of anti-immigration policy at the border, told alongside Olivares' own experience immigrating to the U.S. from Mexico as a young teen.
