Former U.S. Ambassador to Mexico's vision for unity

A former U.S. ambassador to Mexico who's also a fifth-generation Mexican American has a vision for a more inclusive approach to politics. Ken Salazar has also served as a U.S. senator and secretary of the interior. His new book is called "Borderlands: My Fight for an Inclusive America," and it maps out a vision for more unity with our neighboring nations in a time when the U.S. is being defined by our division.
