Edith Windsor is leading the campaign to erase the Defense of Marriage Act, which prohibits the federal government from recognizing same-sex marriages. On Wednesday, the Supreme Court heard oral arguments on her suit, which she filed after she had to pay $363,000 in estate taxes after her female partner died because the federal government didn't recognize their marriage.
