Robert Bowers is on trial for the 2018 Tree of Life synagogue shooting in Pittsburgh, Pennsylvania, which resulted in the death of 11 worshippers. The federal jury trial began Tuesday with 12 jurors and six alternates, and Bowers faces 63 counts, including 11 counts each of obstruction of free exercise of religion and hate crime resulting in death. Prosecutors allege Bowers had "malice and hate" for Jewish people, while the defense argues he was mentally ill and consumed by hatred and rage. The trial is expected to last several weeks and could have a lasting impact on the victims' families and the Pittsburgh community.
