SIOUX FALLS, S.D. (AP) — A federal grand jury has indicted the environmental group Greenpeace and 11 individuals involved in hanging a banner on Mount Rushmore, a federal prosecutor said Tuesday.

Greenpeace trained the protesters, helped transport them and their equipment to the national monument and hired a helicopter to photograph and record the July 8 event in the Black Hills, U.S. Attorney Marty Jackley said.
