Harrison's grandson, Corey, defended them both, stating that they were never in direct contact with Callahan and "it was in our best interests to get him out of there." Interference with business practices In October 2012, A&E Network and the History Channel, along with Harrison and the rest of the show's cast, were sued in Clark County District Court in Las Vegas for interference with business practices by Wayne F. Jefferies, a Las Vegas promoter and the Harrisons' manager, who represented them and "Chumlee" Russell in their television business dealings.

According to Jefferies, this followed a January 2012 report on TMZ that indicated that the Pawn Stars cast objected to the History Channel's launch of the spinoff Cajun Pawn Stars, of which they had been unaware.
