In a September 29, 2015, interview with Fox News's Sean Hannity, McCarthy was asked what the Republicans had accomplished in Congress. He replied by talking about the House of Representatives' special panel investigation into the 2012 Benghazi attack (in which Islamic militants attacked the American diplomatic compound in Benghazi, Libya). Republicans said the purpose of the government-funded committee was purely to investigate the deaths of four Americans. But McCarthy said, "Everybody thought Hillary Clinton was unbeatable, right? But we put together a Benghazi special committee, a select committee. What are her numbers today? Her numbers are dropping. Why? Because she's untrustable. But no one would have known any of that had happened, had we not fought." The comment was seen as an admission that the investigation was a partisan political undertaking rather than a substantive inquiry. Some commentators described his remark as a classic "Kinsley gaffe" (defined as when a politician accidentally tells the truth). the remark was also described as a "" gaffe. Several days later, McCarthy apologized for the remarks and said that the Benghazi panel was not a political initiative.
