Barack Obama has appeared on the cover of Out Magazine, becoming the first sitting US president to be photographed for an LGBT publication.
The photoshoot was conducted in recognition of the magazine's decision to name Obama as its "Ally of the Year" for the gay community, after he helped secure same-sex marriage in the United States.
In the accompanying interview, Obama explains why he felt so strongly that denying homosexual couples marriage was "unconstitutional". The President cites his mother as a champion of inclusivity, remembering how she taught him that "every person was of equal worth".
Obama also acknowledges that the time was right to legalise gay marriage across America, as he has witnessed social changes between his own and his daughters' generations. "To Malia and Sasha and their friends," says the President, "discrimination in any form against anyone doesn't make sense.
"It doesn't dawn on them that friends who are gay or friends' parents who are same-sex couples should be treated any differently. That's powerful."
