I have a lot of friends in South Carolina.

I respect the second amendment and the right of individuals to own firearms. But I think that we all agree that there are some people who should not be able just to walk in and buy weapons of war.

It is our job to figure out what happened and do everything we can to prevent it from ever happening again.

African-American men are more likely to be killed in police incidents, stopped and searched, and sentenced to longer prison terms than white men convicted of similar crimes. Behind these statistics are heart-wrenching stories of lives cut short and families ripped apart.

I'm not interested in, you know, turning the clock back or pointing fingers, but I am interested in trying to figure out how we come together to chart a better way forward and one that will restore confidence in, you know, small and medium-size businesses and consumers and begin to chip away at the unemployment rate.

We have to make our economy work for everyone - not just those at the top - protecting our country and protecting our planet.

I don't think any of us have the answers to everything. There's no human being on earth who fits that category. So why wouldn't you ask for help? Why wouldn't you run ideas by people that you respect? Too many young people cast around trying to figure out what the answer is themselves, because they're afraid to come back and say, "I'm not sure I understood you," or "Could you give me a little more information about what you need?" Just do that. It saves you time, it saves your boss's or mentor's time. And it's a great lesson to learn.
