After the 2018 mid-term elections, in which Democrats won a majority in the House, McCarthy said that Democrats should not investigate President Donald Trump. He described investigations of Trump as a "small agenda", and that "America's too great of a nation to have such a small agenda." He said that Trump had already been investigated "for a long period of time." McCarthy and other House Republicans investigated Hillary Clinton for years over the 2012 Benghazi attack. In 2015, McCarthy said that the investigation, which found no evidence of wrong-doing on Clinton's part, had hurt poll numbers.
