The No. 2 Democrat in the U.S. Senate is calling on legislators in his state to pass legislation that would make Illinois the 10th state in the country to legalize marriage equality. In a letter dated Jan. 3 to state lawmakers, Senate Majority Whip Richard Durbin (D-Ill.) talks about his own evolution on the issue of marriage rights for gay couples, saying he’s concluded that “ending this discrimination” against them is “consistent with the evolution of civil rights in our democracy.” “Every generation is given a chance to put an end to some form of discrimination in America,” Durbin writes. “As you consider this historic vote, I hope you will reflect on those you will meet after it is cast. An affirmative vote will give you a chance to look into the eyes of those who have faced discrimination throughout their lives and tell them that you voted to affirm their rights under the law.” Durbin has previously expressed support for marriage equality and among the members of the Senate Judiciary Committee who voted to report out to the Senate legislation that would repeal the Defense of Marriage Act last year. As a U.S. House member in 1996, Durbin voted in favor of DOMA.
