Running! is a Teen Vogue series on getting involved in the government.

Jackie Fielder, a member of the Three Affiliated Tribes, is only 25, but she’s been pretty busy for the past few years. Fielder is an activist who has campaigned against the construction of the Dakota Access Pipeline; helped organize public banking efforts in San Francisco; and worked to defeat a city initiative that would loosen taser use for police in the Bay Area.
