(Carson City, NV) — A new study gives Nevada low marks for preventing corruption in the state Legislature.

The State Integrity Investigation gives Nevada a grade of D-minus for having procedures in place to prevent wrongdoing by lawmakers.

The Silver State’s legislature meets for just four months every other year, and lawmakers must hold outside jobs to earn a living.

The study found other problems, including “flimsy lobbying reporting requirements,” and loopholes in Nevada’s open meeting law.
