Proposal to alter part of a 2002 law authorizing gambling gaming machines in tribal casinos has gained steam in Idaho congress.

Idaho State Journal reported that lawmakers are targeting to amend the Indian Gaming Regulatory Act, which they say isn’t aligned with the state constitution.

The Idaho Constitution prohibits slot machines across the state while the Indian Gaming Regulatory Act permits tribal casinos to use the gaming machines.

The proposed legislation, which was introduced by House State Affairs Chairman Tom Loertscher, has been discussed in a full hearing on Thursday.
