Bolivian Ambassador Gustavo Guzman, who attended the press conference out of solidarity, said he takes the Lakotas' declaration of independence seriously.

"We are here because the demands of indigenous people of America are our demands," Guzman said. "We have sent all the documents they presented to the embassy to our ministry of foreign affairs in Bolivia and they'll analyze everything."
