The Anti-Defamation League believes today's shooting at a Pittsburgh synagogue was the deadliest attack on the Jewish community in U.S. history. Eleven people were killed at the Tree of Life Synagogue this morning. ADL CEO Jonathan Greenblatt said it's "unconscionable" that Jews would be targeted during worship on a Sabbath morning. He added that it's "unthinkable that it would happen in the United States of America in this day and age." He also noted that his group has reported a historic increase in anti-Semitic incidents and online harassment.
