We must always refill and ensure there is a critical mass of leaders and activists committed to nonviolence and racial and economic justice who will keep seeding and building transforming movements.

It was clear to me as a civil rights leader in the '60s that unless we put the social and economic underpinnings beneath the political and the civil rights, we wouldn't go anywhere.

When President Kennedy was elected, many black Americans, like so many Americans, were captivated by his youth and energy and promise and were especially hopeful that he might move the country in a new direction on civil rights.

It was very clear to me in 1965, in Mississippi, that, as a lawyer, I could get people into schools, desegregate the schools, but if they were kicked off the plantations - and if they didn't have food, didn't have jobs, didn't have health care, didn't have the means to exercise those civil rights, we were not going to have success.

But one of the most enjoyable things for me is that running for office gives you this license to enter the world of somebody else and to hear about the dreams that they have for themselves, for their family, for the country.

OK, I have a nickname. My family calls me 'Trey' because I'm William the third. My dad has the same name, which is always confusing because my dad is well known, and I'm also known.

My parents are aging and there are difficult issues. It's strange to have children at the beginning of life and parents nearing the end.

I come from a poor family.
