Arizona U.S. Attorney Diane Humetewa announced July 28 that she will resign.
Humetewa was appointed by President George W. Bush’s administration after several U.S. attorneys were fired in midterm, including Phoenix lawyer Paul Charlton.
Humetewa is a member of the Hopi Tribe and had been the first American Indian woman to serve as U.S. attorney. Her last day will be Aug. 2.
President Barack Obama has nominated the former chief of staff for ex-Arizona Gov. Janet Napolitano as the next U.S. attorney for Arizona. Dennis Burke served as Napolitano’s chief of staff for more than 10 years before resigning to campaign for Obama in 2008.
The post requires Senate confirmation.
