"[EchoHawk's appointment] helps to obliterate the old myth that you can't be a good Democrat and a member of the LDS Church," said Jim Dabakis, Utah Democratic Party chairman. "It was never true."
Dabakis also hopes EchoHawk's call shows more Utah Mormons that the Democratic Party shares their values.
"Only 9 percent of LDS people [in the state] self-identify as Democrats," Dabakis said. "One of our objectives is to reach out to LDS people and say we are the party of values, and we want your values."
Dabakis said EchoHawk has earned the respect of Republicans and Democrats in Washington and will be missed when he leaves his federal post.
His boss at the Interior Department shared those sentiments.
"With Larry EchoHawk's leadership," Secretary Ken Salazar said in a statement, "we have opened a new chapter in our nation-to-nation relationships with American Indian and Alaska Native tribal governments, accelerated the restoration of tribal homelands, improved safety in tribal communities, resolved century-old water disputes, invested in education and reached many more milestones that are helping Indian nations pursue the future of their choosing."
Interior said EchoHawk is expected to step down after a period of transition to begin his new ecclesiastical role.
Shirlee Silversmith, director of the Utah Division of Indian Affairs, sees EchoHawk's new assignment as good news for all Indians.
"It is a very wonderful honor for native people when we see one of our own people in this position," she said. "I think for those who are of that faith, it is wonderful."
Silversmith, who has met with EchoHawk several times, praised him as a role model for Indian youths, fulfilling the hopes of many tribes.
"Many people are pleased," Silversmith said, "with what he has done on behalf of our tribal nations."
EchoHawk is the second American Indian to be appointed a general authority of The Church of Jesus Christ of Latter-day Saints.
In 1975, George P. Lee, a Navajo, was called to the Seventy by then-LDS Church President Spencer W. Kimball. Lee served for 14 years until he was excommunicated for "apostasy" and "conduct unbecoming a member of the church."
Lee, who later pleaded guilty to attempted sexual abuse of a child, died in 2010 at age 67.
EchoHawk attended Brigham Young University on a football scholarship, playing in every game between 1966 and 1969. He earned Academic All-Western Athletic Conference honors before graduating in 1970. He earned a law degree from the University of Utah in 1973.
After serving as Idaho's attorney general, EchoHawk taught law at BYU's law school.
James Warren "Flaming Eagle" Mooney, an elder with the Oklevueha Native American Church, said EchoHawk is a good man and labeled his LDS Church calling a "good move."
