Kids are falling through the cracks and nobody notices it. That to me is what's wrong with the school system.

We start with an economic approach. We look at what are the greatest causes of death in the developing world, and what causes the largest amount of disability, which would prevent you from getting a job. A lot of those deaths start with diseases, diseases we don't get in such a great number in the United States.

Vaccines are a miracle cure. Eight out of 10 children are getting vaccines.

The biggest pieces of work that we do are vaccines, because those save lives, and also family planning. Because if a woman can space the births of her children, it changes everything for her health and her child's health.

Today is International Women's Day, and there's a fantastic set of pieces running by an organization called ONE called "Poverty Is Sexist." It's a great way to quickly learn about what's actually going on for women in poverty around the world, and then do something about it.

I am Catholic, I was raised Catholic, I am a practicing Catholic. But I say we need to agree to disagree. We have a shared mission around poverty, and I focus on that, because we do a lot with the Catholic Church around poverty alleviation. I'm always looking for: what is the common thread? What do we care about? What do we believe in? We believe in women around the world. We believe in all lives have equal value.

Sanitation issues in the developing world affect women more than they affect men.
