The Man Who Hunted Osama bin Laden

John was among several CIA officials who repeatedly briefed Obama and others at the White House. Current and former officials involved in the discussions said John had a coolness and a reassuring confidence.

By April, the president had decided to send the Navy SEALs to assault the compound. Though the plan was in motion, John went back to his team, a senior intelligence official said.

"Right up to the last hour," he told them, "if we get any piece of information that suggests it's not him, somebody has to raise their hand before we risk American lives."

Nobody did. Inside the Situation Room, the analyst who was barely known outside the close-knit intelligence world took his place alongside the nation's top security officials, the household names and well-known faces of Washington.

An agonizing 40 minutes after Navy SEALs stormed the compound, the report came back: Bin Laden was dead. John and his team had guessed correctly, taking an intellectual risk based on incomplete information. It was a gamble that ended a decade of disappointment. Later, Champagne was uncorked back at the CIA, where those in the Counterterrorism Center who had targeted bin Laden for so long celebrated.

John's team reveled in the moment. Two days after bin Laden's death, John accompanied Panetta to Congress. The Senate Intelligence Committee wanted a full briefing on the successful mission. At one point in the private session, Panetta turned to the man whose counterterrorism resume spanned four CIA directors.

He began to speak, about the operation and about the years of intelligence it was based on. And as he spoke about the mission that had become his career, the calm, collected analyst paused, and he choked up.
