The investigation into the mass shooting in Las Vegas continues to unfold. Erin Delmore, Senior Political Correspondent at Bustle, discusses whether or not we should call the shooting an act of terrorism. She says the police need to confirm certain links to terror groups and a specific ideology in order to give it that name, even though she believes the shooter should be considered a terrorist. She reveals more details about how the shooter was able to pack over 40 guns into the Mandalay Bay hotel room. Plus, how Trump handled the horror. She talks about his plans for the next week after touching down in Puerto Rico Tuesday.
