King and Spalding announced today that they would no longer be representing the House of Representatives in litigation defending DOMA. The House had hired the firm last week after the Justice Department refused to defend the law and Attorney General Eric Holder called it unconstitutional. The chairman of the firm announced that the process “for vetting this engagement was inadequate.” Paul Clement, the lead attorney on the case and former solicitor general under President George W. Bush, announced his resignation ( shortly after the firm’s announcement. In his resignation, Clement expressed his disappointment that the firm was not taking the case because it was “unpopular.” “Defending unpopular positions is what lawyers do,” he said.
