A group of Jamaica Plain educators are part of an organization that is fighting for the rights of undocumented Boston Public School students. Jamaica Plain residents Adriana Costache and Maya Taft-Morales have been working with BTU Unafraid Educators for more than two years, or as Maya Taft-Morales described it -- since Trump was elected. Both fielded questions about their involvement in the organization. Q: What school do you teach in, and what do you teach? Costache: I teach math and science to English learners at Fenway High School.
