After leaving the military, Trudell had become involved in Indian activism. In 1969, he became the spokesperson for the United Indians of All Tribes' occupation of
Alcatraz Island. This was a mostly student-member group that had developed in San Francisco. Trudell went to Alcatraz a week after the occupation started. He used his background in broadcasting and ran a radio station from the island through a cooperative arrangement with students at the
University of California, Berkeley, broadcasting at night over the Berkeley
FM station
KPFA. The show was called
Radio Free Alcatraz. He discussed the cause of the occupation and
American Indian issues and played traditional Native American music. He criticized how "the system today is only geared toward white needs." He spoke for the many Indigenous people who believed they did not fit in with the majority of European-American population of the nation. He became a spokesperson for the occupation specifically and for the Alcatraz-
Red Power Movement generally, as the author
Vine Deloria, Jr. named it. Trudell was the spokesman for the nearly two-year-long occupation, until 1971. After the failure of the federal government to meet demands of the protesters at Alcatraz, Trudell joined the
American Indian Movement. It had been established in 1968 in
Minneapolis among urban American Indians, first to deal with alleged police harassment and injustice in the law enforcement system. Trudell acted as its national chairman from 1973 until 1979. He took the position after the first chairman,
Carter Camp, was convicted for actions related to a protest and was sentenced to jail.
Loss of family in house fire On February 12, 1979, Trudell's wife
Tina Manning, their three children and his mother-in-law, Leah Hicks-Manning, died in a suspicious fire at the home of his parents-in-law on the
Duck Valley Indian Reservation in
Nevada. His father-in-law Arthur Manning survived. He was a member of the
Duck Valley Shoshone Paiute's
Tribal Council which was working for treaty rights. Opponents included the local tribal police chief and the BIA superintendent, John Artichoker. Leah coordinated social services at the reservation. Tina had been working for tribal water rights at the
Wild Horse Reservoir. Opponents of her campaign included officials of the local BIA,
Elko County and Nevada state officials, members of the water recreation industry, and local white ranchers. Other activists have also speculated whether there was government involvement behind the tragedy. The house fire that killed Trudell's family happened within 24 hours of him burning a US flag on the steps of the FBI building in Washington D.C. in protest of the government's treatment of Native Americans and the Sioux Nation. Trudell believed that the fire was meant to threaten and silence him and his activist wife.
Aquash murder controversy In 2004, Trudell testified in the federal trial of
Arlo Looking Cloud, an
Oglala Lakota American Indian Movement (AIM) member charged in the kidnapping and murder of
Anna Mae Aquash, the highest-ranking woman in AIM, in December 1975. Trudell testified that Looking Cloud had told him that
John Graham, another low-level AIM member, was the gunman in the murder. Trudell identified Graham from photographs. Looking Cloud was convicted in 2004 and sentenced to life imprisonment. His testimony was part of the evidence considered by the Canadian judge who ordered Graham's extradition to the United States in February 2005. On March 2, 2005, the Native Youth Movement Vancouver announced a boycott of Trudell's music and poetry in retaliation for his testimony and alleged that the FBI had killed Aquash. In 2010, Graham was convicted in a South Dakota state court of felony murder of Aquash and sentenced to life imprisonment.
Later years Trudell was the co-founder, with
Willie Nelson, of Hempstead Project Heart, which became a project of
Earth Island Institute in 2012. Hempstead Project Heart is dedicated to raising awareness about the environmental, social, and economic benefits of legalizing
industrial hemp in America. Trudell was also involved with
Seva Foundation and their Native American programs. He performed at numerous benefit concerts in support of their work. ==Personal life==
