The Senate campaign for Rep. Joe Donnelly, D-2nd, announced Thursday the formation of Gun Owners for Donnelly.
The eight-member group includes Jim Paxton, detective lieutenant for the Wells County Sheriff's Department.
"I am glad we have someone like Joe who is truly concerned about the rights of gun owners as well as the rights of everyone in Indiana," Paxton said in a statement.
Other members include state Rep. Terry Goodin, D-Austin, and Vanderburgh County Sheriff Eric Williams.
Donnelly is unopposed in the May 8 Democratic primary election. Sen. Richard Lugar, R-Ind., is being challenged by state Treasurer Richard Mourdock in the Republican primary.
