"I am convinced that every abortion is an unplanned tragedy, brought about by a combination of human errors and this has been one of the most difficult moral and political issues I have had to face. As president, I accepted my obligation to enforce the "Roe v. Wade" Supreme Court ruling, and at the same time attempted in every way possible to minimize the number of abortions. One of my best-remembered and most often quoted remarks came in July 1977, when I defended my lack of support for federal funds to be used for abortions among poor mothers, even though wealthier women could afford to have their pregnancies terminated. Without any careful forethought, I responded to a question on this issue by saying, "Life is often unfair.""
