WINNEBAGO, Neb. (AP) — An election has been scheduled to replace three Winnebago tribal council members who resigned after an investigation showed that council members had given themselves raises and bonuses.

The election is set for May 5.

Council members Travis Mallory and Morgan Earth resigned in March, and chairman John Blackhawk resigned last week, ending his 20 years as chairman of the nine-member council.

A tribal investigative committee released its report in February detailing the allegations. It said the council gave itself salary increases of 35 percent in fiscal year 2013 and that at least one council member gave loans to family members. The committee said it also found that council members received bonuses with no evidence that those bonuses were approved by the council.
