California ? Slain gay rights activist Harvey Milk will get a special day of recognition in California, making him only the second person in state history — in addition to conservationist John Muir — to gain such a designation.

Gov. Arnold Schwarzenegger’s signing of the bill establishing “Harvey Milk Day” each May 22, Milk’s birthday, was announced Monday.

The Republican governor vetoed similar legislation a year ago. In the interim, Milk was posthumously awarded the Presidential Medal of Freedom in August and was the subject of a movie for which Sean Penn won the Academy Award for best actor.

Penn spoke out in favor of the bill last spring, saying he didn’t want to insult Schwarzenegger’s intelligence by assuming the governor would again oppose creating Harvey Milk Day.

Milk was a leader in the gay rights movement who was elected to the San Francisco Board of Supervisors in 1977. The bill said he was the nation’s first openly gay man elected to public office in a major U.S. city.
