BILLINGS, Mont. (AP) — An elder from Montana's Crow Indian Tribe whose family ceremoniously adopted then-Sen. Barack Obama during the 2008 presidential race has died.

Hartford "Sonny" Black Eagle Jr. died Monday at his home in Lodge Grass on the tribe's reservation in the southeastern part of the state, said his son, Crow tribal Chairman Cedric Black Eagle.

The 78-year-old traditional healer died in his sleep after battling respiratory problems stemming from a severe case of pneumonia several months ago, Cedric Black Eagle said.

President Obama called Black Eagle's wife, Mary, on Wednesday to express his condolences, a White House official said.

Black Eagle and his family adopted Obama when the presidential candidate visited the reservation in the weeks leading up to Montana's Democratic primary.

As part of the adoption, Obama attended a purification ceremony where he faced east, the symbolic source of new life, and was prayed over by Black Eagle. He was given a Crow name that translates as "One Who Helps People Throughout the Land."

Cedric Black Eagle said his father considered the 2008 adoption ceremony one of the proudest moments in his life and subsequently considered it his duty to make sure Native American voices were heard.

"He felt like he was representing all of Indian Country as a spokesman, and always telling his (adopted) son, the president, that he has to make sure all of the people in Indian Country are heard and try to help them all," Cedric Black Eagle said.

Obama, who referred to himself as "Barack Black Eagle" during his 2008 visit to Crow Agency, pledged at the time to improve relations between American Indian tribes and the federal government if elected.

Black Eagle and his wife were later invited to Obama's presidential inauguration, and returned to Washington, D.C., in subsequent years for the annual White House Tribal Leaders Conference. Black Eagle and other family members also attended several Christmas dinners at the White House, his son said.

During destructive flooding on the reservation last year that left Lodge Grass largely isolated and forced many tribal members from their homes, Obama called Hartford and Mary Black Eagle to check on their safety, Cedric Black Eagle said. Continued...
