BOISE, Idaho (AP)  — A rule change unraveled a legislative committee Thursday as Idaho lawmakers expressed dismay over the state's increasingly slot-like machines, known as instant horse racing terminals.

    House State Affairs Committee members held off approving a rule seeking to slow the proliferation of instant racing machines in Idaho. According to the proposed rule, licensees would be required to have a simulcasting license, which allows broadcasting live races occurring elsewhere, before they could install instant racing machines.
