Delaware Attorney General Beau Biden appears in a video ad endorsing an effort to legalize gay marriage in the state.

In the 60-second ad, Biden, the son of Vice President Joe Biden, calls marriage equality “the fundamental, defining civil rights issue of our time.”

“Any effort to dictate who we love and to whom we commit ourselves is unfair and it is wrong,” Biden, a Democrat, said. “All Delawareans should be able to marry the person they love.” (The video is embedded on this page. Visit our video library for more videos.)

Delaware currently recognizes gay and lesbian couples with civil unions. A marriage bill is expected to be introduced in the Legislature this spring.

“Attorney General Biden has always been a steadfast champion for treating every citizen equally under the law,” Lisa Goodman, president of Equality Delaware, the group behind the ad, told “To have his support – as our highest law enforcement official and as a veteran – is a true honor. The momentum continues to grow as we anticipate a marriage bill in the coming weeks.”
