Nathan Phillips is a US Marine Corps veteran, an Omaha Native American political activist also known as Sky Man, and former Director of the Native Youth Alliance, a group aiming to uphold traditional culture and spiritual ways for future Native Americans.

In the late 1990s Nathan was working to create a foster care system run by American Indians for American Indian children to help them gain an appreciation for their heritage: "I don't want our children to think that prison is the only place for them to go."

Phillips was among the last of the protesters when law enforcement evicted the camps and effectively ended the protests, which for his part were "a prayer (...) a commitment to stand for our youth, for our children, for nature and for myself, standing for my nation."
