Donell Harvin, former DC Chief of Homeland Security and Intelligence and current faculty member at Georgetown University's School of Foreign Service, calls the shooting at Saturday's White House Correspondents' Dinner a "near miss," warning the president being within earshot of gunfire is "too close" and highlighting how "unprecedented" it is for one president to face three separate assassination attempts. He says the lack of a National Special Security Event designation and the concentration of top officials in one venue exposed vulnerabilities, even as he says the Secret Service response 'did exactly what it is supposed to do. He speaks with Kailey Leinz and Joe Mathieu on the late edition of Bloomberg's "Balance of Power." (Source: Bloomberg)
