He comes with an enormous amount of good will. I mean, people have really seen him stand up in strikes and organizing drives and things that most vice presidents of the United States have never done, and that is enormously appreciated and gives him a lot of credit.

Our unions do a large amount of organizing in parts of the economy that historically and recently are places where people of color and immigrant workers have found jobs. Some of them are entry-level jobs. Throughout history immigrants have found work as janitors, and our unions have helped them raise families, send their kids to college, and that's been the American dream.

They've shown an incredible amount of courage, and I thought it was time to pass on the responsibility to other leaders in the union.

How do we take the different assets that different unions bring to the table and use them strategically? American Unions, for example, have a disproportionate amount of resources, while other unions have political power, and if we think together we may be able to use the global economy to our advantage.
