In late 2017, Lindberg became frustrated with the lending limits placed on the assets of his insurance firm, Global Bankers Insurance Group, by North Carolina Deputy Commissioner of Insurance Jackie Obusek. After several heated exchanges with Obusek, Lindberg and two business associates, John Gray and John Palermo Jr., began meeting with North Carolina Commissioner of Insurance Mike Causey, a Republican, to discuss Obusek's position in regulating the insurance firm.[15] Lindberg suggested that Palermo be hired by Causey to regulate his companies.[22] By January 2018 Causey had informed law enforcement officials of the meetings[15] and he began assisting the Federal Bureau of Investigation as the agency investigated Lindberg's entreaties. Over the course of the discussions, Lindberg ultimately donated about $250,000 to the North Carolina Republican Party.[22]
On March 18, 2019, Lindberg, Gray, and Palermo, along with the chair of the North Carolina Republican Party, Robin Hayes, were indicted by a federal grand jury[18] for financial crimes including wire fraud and bribery.
