The man who killed Usama bin Laden was on “Fox and Friends” this morning on the fourth anniversary of the al Qaeda leader’s death.

On May 1, 2011, President Barack Obama announced to the world that bin Laden had been killed by U.S. forces in a special operation.

“We can say to those families who lost loved ones to al Qaeda's terror: justice has been done," Obama told the nation.

Navy SEAL Rob O’Neill is credited with firing the shots that killed bin Laden.

“When I close my eyes I can still see him standing there,” he said today on "Fox and Friends."

O’Neill called that mission “the most important thing I’ve ever been a part of.”

“I was lucky to be a part of that team,” he said.

Watch O'Neill's interview above. Below, take a look back at the historic remarks that Obama made four years ago.
