Clinton asks justices to overturn law he signed

It’s not every day that an ex-president asks the Supreme Court to strike down a law he signed.

That’s what Bill Clinton did with the Defense of Marriage Act, which defines marriage as between a man and a woman—and which the high court will rule on this year in a landmark moment for the gay marriage movement.

The justices must decide whether the Defense of Marriage Act “is consistent with the principles of a nation that honors freedom, equality and justice above all, and is therefore constitutional,” Clinton wrote in the Washington Post. He adds: “As the president who signed the act into law, I have come to believe that DOMA is contrary to those principles and, in fact, incompatible with our Constitution.”
