The director of the Interior Department's Bureau of Indian Affairs has resigned after only six months on the job, HuffPost reported Thursday.

The resignation from bureau head Bryan Rice came just over two weeks after the Interior Department's inspector general released a report saying that the agency had failed to gather sufficient information to determine whether the reassignments of dozens of senior officials were legal.

Nedra Darling, a spokeswoman for the bureau, did not immediately respond to The Hill's request for comment on Rice's resignation.

"It is our policy not to discuss DOI personnel matters in the press," she wrote in an email to HuffPost.

Rice, a member of the Cherokee Nation of Oklahoma, was a veteran official at the Bureau of Indian Affairs before his appointment as the bureau's director in October.

The Bureau of Indian Affairs handles relations between the federal government and 573 federally recognized tribes.
