Non-Islamic, non-foreign-motivated terrorist actions have killed at least as many Americans on American soil as those who were promoted by jihadists. But what we have also seen is ISIL evolve, because of the sophistication of their social media, to a point where they may be inspiring more attacks - even if they're self-initiated, even if they don't involve complex planning - than we would have seen some time ago.

Muslim leaders around the globe have to continue working with us to decisively and unequivocally reject the hateful ideology that groups like ISIL and al Qaeda promote. To speak out against not just acts of violence, but also those interpretations of Islam that are incompatible with the values of religious tolerance, mutual respect, and human dignity.

I think there is nothing wrong with instituting policies that say that harassment of any form, whether it comes through the Internet or whether it happens to you face to face, is unacceptable; that we've got zero tolerance when it comes to sexual harassment, we have zero tolerance when it comes to harassing people because of their sexual orientation, because of their race, because of their ethnicity.

The United States does not have a monopoly on crazy people. It's not the only country that has psychosis. And yet we kill each other in these mass shootings at rates that are exponentially higher than anyone else. Well, what's the difference? The difference is that these guys can stack up a bunch of ammunition in their houses, and that's sort of par for the course.
