California governor signs bill requiring schools to teach gay history

Los Angeles (CNN) -- Democratic California Gov. Jerry Brown said Thursday he had signed a bill that will require public schools in the state to teach students about the contributions of lesbian, gay, bisexual and transgender Americans.

The bill, believed to be the first of its kind in the nation, will also require teachers to provide instruction on the role of people with disabilities.

"History should be honest," Brown said in a statement.

"This bill revises existing laws that prohibit discrimination in education and ensures that the important contributions of Americans from all backgrounds and walks of life are included in our history books. It represents an important step forward for our state, and I thank Senator Leno for his hard work on this historic legislation."
