'Winter of Love': 20th anniversary of same sex-marriage in San Francisco

Monday marked the 20th anniversary of a pivotal moment that took place in San Francisco in the legal battle for marriage equality for same-sex couples. It's remembered as the Winter of Love when San Francisco began issuing marriage licenses to same-sex couples. Then mayor Gavin Newsom defied the federal ban on gay marriage and put into motion a nearly decade-long legal battle on the road to the Supreme Court's landmark ruling in 2013.
