Nebraska lieutenant governor resigns after 2,300 late-night calls exposed By Mary Wisniewski, Reuters Nati Harnik / Associated Press photo Nebraska Lieutenant Governor Rick Sheehy resigned Saturday after newspaper reporters uncovered thousands of late-night phone calls he had made to women other than his wife. Nebraska Lieutenant Governor Rick Sheehy, once favored to replace the current governor in 2016, resigned Saturday after newspaper reporters approached his office about thousands of late-night phone calls he had made to women with his state-issued cell phone. Reporters Paul Hammel and Robynn Tysver of the Omaha World-Herald filed public records requests with Sheehy's office in December for his work cell phone records. The state gave the reporters those records in January. The reporters then spent a month on the story, uncovering the 53-year-old Republican's secret life. They found that he had made 2,300 late-night calls to four women - not one his wife - over the last four years. Read the Omaha World-Herald report Colleen Sheehy, his wife of 28 years, filed for divorce in July, the Omaha World-Herald reported. Most of the calls were made before then, however. Governor Dave Heineman announced his lieutenant's resignation on Saturday. I've got a knot in my stomach. I'm deeply disappointed," Heineman said at a press conference on Saturday, according to the Omaha World-Herald. He's done a lot of good things for the state, but that trust was broken, and he's resigned. The four women included two well-known former elected officials. One was a doctor who told the Omaha newspaper that she and Sheehy had seen each other for four years, and that Sheehy had promised to marry her. He spent a total of 406 hours on the phone with another woman. In July 2011, Sheehy spoke with two of the women for nearly 17 hours. The Omaha World-Herald noted that he spoke with his wife just 14 times that month - no longer than five minutes each time. Sheehy had announced he would run for governor in 2016, after Heineman left office. Sheehy was tapped as lieutenant government in 2005.
