Mark Souder, a self-described “ultraconservative” Republican who represented northeastern Indiana in Congress for more than 15 years before resigning in 2010 after his extramarital affair with a female aide came to light, died Sept. 26 at 72.

His family announced the death. Mr. Souder disclosed in January that he had inoperable pancreatic cancer.
