The Glarners have denied that the donations and the contract were related. They did not respond to a request to their lawyer for comment on Monday.

Next on Goldsmith’s list are two businesses — Cardinal Insurance Group and Brentwood Capital Partners — associated with businessman John Rallo.

He and partner Corey Christanell were investors with Wellston Holdings, which bought two Wellston industrial parks from the St. Louis County Land Clearance for Redevelopment Authority for a little more than $525,000. Rallo, Christanell and companies they are associated with have donated around $40,000 to Stenger’s political campaign.

Stenger has repeatedly denied any involvement in the 2017 deal. But the St. Louis Economic Development Partnership official who oversaw the sale told the newspaper in December that Rallo’s relationship with Stenger was central to the bidding process, and that he had been told not to find other bidders for the sites. Rallo and Christanell did not respond to a request for comment.
