"I commend Secretary Napolitano for recognizing the value and importance of all families,” Leahy said Monday in a press release. “Her actions in this regard represent another step toward fairness and equality under our immigration law, and most of all it is the right thing to do."  

The announcement followed the administration’s decision in June to defer action for qualifying young people brought to the country illegally by their parents.

“I praised President Obama and Secretary Napolitano in June for rightly embracing a temporary relief policy for qualified young people, brought here through no fault of their own, and I again commend them for extending the same opportunities for relief to qualifying same-sex couples,” Leahy said.

Leahy has introduced the United American Families Act, which would make Napolitano’s decision on same-sex relationships permanent.
