CNN speaks with the Wilfahrt family about their son, Cpl. Anthony Wilfahrt, who was killed in February in Afghanistan. Cpl. Wilfahrt was openly gay, a fact that seemed not to affect the other guys in his unit. CNN's Wayne Drash has written a poignant profile of Cpl. Wilfahrt and the effect his death had on his family.
Now Wilfahrt's parents have taken up the cause of same-sex marriage on his behalf. A proposed change to the state constitution in Minnesota, where the Wilfahrts are from, would outlaw gay marriage and define the union as one man and one woman. CNN also speaks with the man who authored the proposed amendment, State Sen. Warren Limmer.
