I've taken my knocks here and there, but I believe my intentions are good. Doesn't mean everything I do is perfectly executed or I don't make mistakes. Of course I do.

Progress is the product of human agency. Things get better because we make them better. Things go wrong when we get too comfortable, when we fail to take risks or seize opportunities.

The larger picture here is that a North Korea with nuclear weapons adds to the larger proliferation risk.

It may not be what you would've chosen, but we all have a responsibility to be active citizens and shape our system and our future.

I don't have time to think about the false controversy.

You have to make change.
