A second lawsuit has been filed containing an identical allegation that Sen. Norm Coleman’s long time political patron funneled $75,000 that was intended to benefit the Senator to a Minneapolis insurance firm, the Star Tribune reports. The case was filed Friday in Delaware Chancery Court and attributes the Coleman claim to a “confidential source.”

The lawsuit was brought by minority shareholders of Deep Marine Technology, a Houston-based firm that provides underwater services to oil companies. It alleges that Nasser Kazeminy utilized the firm to funnel $75,000 to the Republican senator through payments to his wife, Laurie Coleman, via the Minneapolis insurance company where she works.

Sen. Coleman has denied the allegation, calling it a “sleazy” political attack, and blaming the controversy on his Democratic opponent. Al Franken’s campaign has denied any connection to the lawsuit.

Paul McKim, the founder of Deep Marine Technology, who filed the initial lawsuit in Texas on Monday, insists that the dispute is not politically motivated. In fact, he claims to have never heard of Coleman prior to the dust-up with Kazeminy. “It’s just weird timing with Senator Coleman and all this,” McKim tells the Pioneer Press. “I know how it must look, but it’s really not political. I feel bad for him and his family. I don’t know the gentleman, and I’m not a political guy. I’m just an old deep-sea diver. And I’m a Republican.”

In a twist, McKim is actually named as a defendant in the second lawsuit.
