The American ambassador in Denmark Rufus Gifford, right, waves next to his partner Stephen DeVincent after they got married at Copenhagen City Hall in Copenhagen. The U.S. ambassador to Denmark has married his partner in the Scandinavian country that became the first nation to allow gay couples to formalize their unions in 1989. Rufus Gifford, the U.S. envoy since September 2013, is a strong gay rights advocate and often appears with Stephen DeVincent, a 56-year-old veterinarian, at his side. The two were married at the Copenhagen City Hall. Gifford, a 41-year-old Boston native, wrote on Twitter: "26 yrs ago the site of 1st legal gay unions in the world. Humbled and emotional."
