The Senate passed a bill that would make it illegal for insurance companies to deny policies or charge higher rates solely based on gun ownership.
The bill passed on a 36-3 vote.
Supporters have said some insurance companies would prefer not to insure gun owners and others have a different set of rates. They want to make it illegal to discriminate against citizens who are exercising their constitutional right to own firearms.
Some insurance companies say there is greater risk of claims from gun owners.
A similar House bill is waiting for a floor vote.
