Kansas City, Kan. ? Court records show that independent Senate candidate Greg Orman is embroiled in a federal lawsuit in Kansas with an international boxing equipment manufacturer.

The dispute with Everlast World’s Boxing Headquarters Corp. involves $30 million worth of payments for royalties and merchandise sales that the firm claims it will be owed through 2018.

Orman hopes to unseat three-term Republican Sen. Pat Roberts in the Nov. 4 election.

He is one of five defendants in the lawsuit filed by Everlast, initially in 2012. It is scheduled to go to trial in October 2015.

The lawsuit alleges Orman and the others remain responsible for payments owed to Everlast by a now-bankrupt Lenexa company because they formed new firms to take over its sales. Orman and the other defendants deny those claims.
