Another Republican senator has come out in support of homosexual marriage.
The announcement from Sen. Mark Kirk. R-Ill., comes less than three weeks after Ohio's Sen. Rob Portman became the first Republican in the Senate to say he supports gay marriage.
It also comes one week after the U.S. Supreme Court heard two days of arguments on the subject.
Kirk suffered a stroke in January 2012. He said that experience made him realize that people should be able to love whoever they want without the government stopping them.
"Our time on this Earth is limited; I know that better than most," Kirk said. "Life comes down to who you love and who loves you back - government has no place in the middle."
Kirk's announcement also comes as the state legislature is giving final consideration to a measure that would make Illinois the 10th state in the nation to allow same-sex marriage.
