"In the fall of 2009, NSA using 702 authority intercepted an e-mail from a terrorist located in Pakistan. That individual was talking with an individual located inside the United States, talking about perfecting a recipe for explosives. Through legal process, that individual was identified as Najibullah Zazi. He was located in Denver, Colorado.

The FBI followed him to New York City. Later we executed search warrants with the New York Joint Terrorism Task Force and NYPD and found bomb-making components in backpacks."
