Nine years ago today, President Barack Obama signed the Lilly Ledbetter Fair Pay Act into law, restoring working women’s right to sue over pay discrimination. It was the first piece of legislation enacted during his presidency, and he noted the significance of the moment: "It is fitting that with the very first bill I sign...we are upholding one of this nation’s first principles: that we are all created equal and each deserve a chance to pursue our own version of happiness."
