Obama 1st president on LGBT cover

President Barack Obama graces the cover of Out, making him the first sitting U.S. president to be featured on an LGBT magazine cover.

Obama is among the magazine's 'list of 100' and is the "Ally of the Year.'

"A president who came to office on a wave of euphoria, appeared to lose momentum halfway through... has since rallied, helping us secure marriage equality, among other landmark initiatives that are transforming our place in America," wrote Editor-in-chief Aaron Hicklin.

Olympian Caitlyn Jenner and actress Raven Symone are also included in Out's 'list of 100.'
