Same-sex marriage supporters wave a rainbow flag in front of the US Supreme Court on March 26, 2013 in Washington, DC. The US Supreme Court on Tuesday takes up the emotionally charged issue of gay marriage as it considers arguments that it should make history and extend equal rights to same-sex couples. Waving US and rainbow flags, hundreds of gay marriage supporters braved the cold to rally outside the court along with a smaller group of opponents, some pushing strollers. Some slept outside in hopes of witnessing the historic hearing. AFP PHOTO/Jewel Samad        (Photo credit should read JEWEL SAMAD/AFP/Getty Images)
