U.S. Atty. Diane Humetewa

Diane Humetewa, the nation’s first female Native American U.S. Attorney, will step down Aug. 2, the  Phoenix Business Journal reported.

The move comes as no surprise since Dennis Burke has already been tapped as her replacement.

Humetewa, a  member of the Hopi Indian Tribe,  began serving in  December 2007.

At the time of her appointment by President Bush,  Indian Country Today newspaper wrote that “Indian country found big reason to celebrate.”
