LAS VEGAS (AP) — A gun control lobbying organization is adding Nevada to efforts to show gun rights groups including the National Rifle Association are behind a "Second Amendment sanctuary" drive in several Western U.S. states.

The Brady national advocacy group said Tuesday it's filing freedom-of-information requests for communications involving Douglas, Elko, Lyon and Nye county commissioners, and Eureka, Pershing and Nye county sheriffs.

Brady president Kris Brown says commissions and sheriffs have "gone rogue" in declaring they won't enforce a new Nevada law calling for strict background checks.

Organization spokesman Max Samis says the effort follows similar information requests last month in New Mexico.

NRA and Nevada Firearms Coalition officials didn't immediately respond to messages.

Nye County Sheriff Sharon Wehrly says she wants to see what Brady is seeking before she comments.
