Joe Biden’s long advocacy for gay rights reached a historic moment when the president-elect named former South Bend, Ind., mayor Pete Buttigieg as his transportation secretary. If confirmed, Buttigieg will become the first openly LBGTQ Cabinet member. But Biden’s support of the gay community has at times caused a stir. At a sensitive moment in 2012, then-Vice President Biden inadvertently prodded his boss, President Barack Obama, to speed up his public affirmation of same-sex marriage.
