HELENA, Mont. (AP) – U.S. government auditors are expanding their review of federal disaster aid mismanagement by the Chippewa Cree Tribe to include all $31.6 million awarded after flooding damaged the Rocky Boy’s reservation in 2010.

The Department of Homeland Security’s inspector general’s office audited one flood-related project for fraud and waste – the demolition of the reservation’s flood-damaged health clinic. The auditors recommended in a report this month that FEMA deny the Montana tribe’s $3.9 million claim.

The auditors say they will now examine all $31.6 million awarded to the tribe that year. They recommend FEMA label the tribe high-risk, meaning future grants would be subject to strict conditions.

FEMA has 90 days to respond.

Chippewa Cree officials blamed the problems on Tony Belcourt, the former tribal construction company CEO convicted of embezzlement last year.
