Pro bono Work to Empower and Represent Act of 2017 or the POWER Act This bill requires each U.S. Attorney for each judicial district to lead at least one public event that promotes pro bono legal services as a critical way to: (1) empower survivors of domestic violence, dating violence, sexual assault, and stalking; and (2) engage citizens in assisting those survivors. A similar requirement applies to districts containing Indian tribes and tribal organizations. Each U.S. Attorney shall: (1) have discretion on the design, organization, and implementation of such public events; and (2) seek to maximize an event's local impact and the access of such survivors to high-quality pro bono legal services.
