The label of radical Islamic terrorism has become a political football, even in the wake of the attack in Orlando that left 50 people dead. Regardless of political posturing, 91 Americans have been killed in the United States by perpetrators motivated by radicalized Islamic beliefs since Obama assumed the office of the Presidency.
Here is a grim history of the last seven years of Islamist attacks of American soil.
