Taking the name Native American Committee (NAC), the group wanted the AIC both to establish more institutional and expansive educational offerings and to use more confrontational, direct-action tactics.
[6] In 1991, Faith Smith described the cultural divide that had formed within the AIC as herself and others wanting to re-focus AIC on "poverty and the problems of Indians on the streets," while many of the existing members continued to feel that “the center ought to be more of a middle-classy sort of thing, a social center or that sort of stuff.
"[8] In 1970, NAC incorporated as an independent organization in Illinois, although many members continued also to work at or belong to the AIC.
Borrowing a ceremonial teepee from the AIC, NAC activists took up residence next to the baseball stadium and successfully drew attention to Warrington's cause and to the poor living conditions for many Native American Chicagoans.
Michael Chosa led the remaining campers out of NAC under the new name Chicago Indian Village (CIV) in a protest that continued in various locations until 1972.
