In an interview aired Sunday on 60 Minutes, President Barack Obama discussed the killing of terror mastermind Osama bin Laden. 

Here are some notable quotes from the interview:

"As nervous as I was about this whole process, the one thing I didn't lose sleep over was the possibility of taking Bin Laden out. Justice was done. And I think that anyone who would question that the perpetrator of mass murder on American soil didn't deserve what he got needs to have their head examined."

"Well, it was certainly one of the most satisfying weeks not only for my presidency, but I think for the United States since I've been president. Obviously Bin Laden had been not only a symbol of terrorism, but a mass murderer who's had eluded justice for so long, and so many families who have been affected I think had given up hope."

"Obviously we have extraordinary guys. Our Special Forces are the best of the best."

"The thing about gut instinct is if it works, then you think, 'Boy, I had good instincts.' If it doesn't, then you're gonna be running back in your mind all the things that told you maybe you shouldn't have done it. Obviously I had enough of an instinct that we could be right, but it was worth doing."

"I made the decision Thursday night, informed my team Friday morning, and then we flew off to look at the tornado damage. To go to Cape Canaveral, to make a speech, a commencement speech. And then we had the White House Correspondents' Dinner on Saturday night. So this was in the back of my mind all weekend."

"And during the course of the weekend, you know, there was no doubt that this was weighing on me. But, you know, something I said during the campaign that I've learned over and over again in this job is the presidency requires you to do more than one thing at a time. And it is important for you to be able to focus on something that matters deeply to you, but still be able to do the things on a daily basis that are making a difference in people's lives."

"And you know, there were big chunks of time in which all we were doing was just waiting. And it was the longest 40 minutes of my life with the possible exception of when Sasha got meningitis when she was three months old, and I was waiting for the doctor to tell me that she was all right. It was a very tense situation."
