Anti-gay California State Senator Roy Ashburn was arrested Wednesday morning for drunk driving shortly after leaving a gay bar in Sacramento, local CBS affiliate CBS13 reported.

Police stopped Ashburn's state issued vehicle after they witnessed the car swerving erratically and charged Ashburn with driving under the influence.

CBS13 reports an unidentified man was in the car with Ashburn, who had that night been at Faces, a popular Sacramento gay bar.

Ashburn, a Republican who has campaigned on a family values platform and a father of four, has a history of opposing gay rights. He scored zero on Equality California's 2009 Legislative Scorecard, a gay rights record issued by the state's leading advocate.

During the 2009 legislative session, Ashburn voted against a resolution that urged repeal of Proposition 8, the state's gay marriage ban, a bill that proclaims May 22nd as Harvey Milk Day in memory of San Francisco's first openly gay politician, and a measure that would allow transgender people to obtain a court order reflecting their correct gender, among others.

Ashburn, who was freed on a $1,400 bond after spending 8 hours in jail, issued an apology: “I am deeply sorry for my actions and offer no excuse for my poor judgment. I accept complete responsibility for my conduct and am prepared to accept the consequences for what I did.”
