At age 25, Gaby Pacheco was the first undocumented Latina to testify in front of Congress. In this conversation with New York Times Contributing Op-Ed Writer Wajahat Ali, she talks about the struggles immigrants still face years later. She spearheaded efforts that led to the Deferred Action for Childhood Arrivals (DACA) program and participated in the Trail of Dreams, a four-month walk from Miami to Washington, DC, calling attention to the plight of immigrants. In this one-on-one conversation, she speaks with Ali about her frustrations with the Trump administration, the challenges facing immigrants who want to become citizens, and the crisis at the US-Mexico border. Pacheco and Ali were speakers at the Aspen Ideas Festival in June.
