Chicago Mayor Rahm Emanuel said Wednesday that he will lobby on behalf of a gay marriage bill, the Chicago Tribune reported.

“I'll push for it because it is consistent with the values base, and the practical values base, that I think it is right as a city, as a state and as a country,” Emanuel said.

The bill, which would make Illinois the eighth state to legalize gay marriage, was introduced last week by openly gay Representatives Greg Harris, Deb Mell and Kelly Cassidy.

Emanuel last year supported passage of a civil unions bill and officiated over the civil union of a staffer on the law's first day.

The 52-year-old Emanuel is also an inaugural member of Mayors for the Freedom to Marry, a group of more than 80 U.S. Mayors who have pledged to support marriage equality.

“If you have two loving adults, that should actually be held up as a positive, whether it's male or female, but in this case female-female, male-male,” Emanuel added. “I think that's proper, and we shouldn't as a state discriminate.”
