SALEM, Ore. (AP) — One of only a few boarding schools for Native American students still run directly by the federal government in Oregon is undergoing a close look at the school’s finances by the Interior Department’s Office of Inspector General.

The office confirmed last month in an email to Oregon Public Broadcasting that it had “initiated an audit of the financial management and financial oversight of the Chemawa Indian School.”

The audit came in response to Democratic U.S. Sens. Ron Wyden and Jeff Merkley, who requested the inquiry after they felt stymied in their own efforts to look into alleged problems at the school.
