A Billings, Montana, man who once served as a tribal government official for the Mandan, Hidatsa and Arikara Nation, or MHA Nation, was sentenced to six years and three months in prison for his part in a bribery scheme.

The U.S. Department of Justice said in a press release on Monday that Frank Charles Grady, 54, was part of a bribery scheme that consisted of accepting bribes and kickbacks from a contractor that provided construction services at Fort Berthold Indian Reservation in North Dakota.

Court documents show Grady, in 2016 and 2017, served on the Tribal Business Council of the MHA Nation.

During that time, Grady sought out and accepted more than $260,000 in bribes and kickbacks from a contractor.

In return, Grady would use his elected power to help the contractor by awarding contracts, creating fake bids during the competitive bidding process, advocate for the contractor to the other Tribal members, and facilitate the payment of fake invoices, the DOJ said.
