Sen. Mark Kirk of Illinois announced his support Tuesday for gay marriage, becoming the second Republican to endorse marriage equality for same-sex couples.
Kirk, who recently returned to Congress after suffering a stroke, joins Sen. Rob Portman of Ohio as the only sitting Republican senators to support gay marriage. Kirk's announcement comes a week after the Supreme Court heard arguments challenging gay marriage in two court cases.
"Same-sex couples should have the right to civil marriage," Kirk said in a statement. "Our time on this earth is limited, I know that better than most. Life comes down to who you and love and who loves you back -- government has no place in the middle."
