When the Constitution was written, the founders had no way of anticipating the new technologies that would evolve in the coming centuries.

When people talked about protecting their privacy when I was growing up, they were talking about protecting it from the government. They talked about unreasonable searches and seizures, about keeping the government out of their bedrooms.

I felt like the luckiest kid in the world. And I was. I was growing up middle-class in a time when growing up middle-class in America meant there would be jobs for my parents, good schools for me to prepare myself for a career, and, if I worked hard and played by the rules, a chance for me to do anything I wanted.

There's an appeal to the American sense of exceptionalism, that we're morally superior, as way to not be self-critical. I think that's a bit dangerous.

I really think that Muslim people should stop raising their boys and girls that way. They instill a macho culture right from the start of childhood.

That's what people are talking about.

I didn't come from a wealthy family. My dad told us if we wanted spending money, we had to earn it. So I developed an early work ethic.
