Staff ReportNewsWest 9A new twist in the controversy over a local credit union's possible conversion to a bank. First Basin Credit Union has suspended voting by its thousands of members after allegations of voting irregularities surfaced. President Shem Culpepper says they are currently investigating those irregularities. Credit Union Officials say converting to a bank would allow First Basin to give out more loans and serve more West Texans. But it has to be approved by First Basin members. A group of union members called "Save First Basin" believe becoming a bank will cost members more money and take away their say in how the organization is run. "Save First Basin" has mounted a campaign to stop the conversion.
