Did A Top GOP Staffer For Sen. Grassley Cover Up Evidence Of News Corp Hacking In The U.S.? | ThinkProgress In 2006, Grassley was chairman of the Senate Finance Committee, and Emmel had gone to the committee looking for help. According to court filings, Grassley investigative staffer Nick Podsiadly had spoken with Emmel and told him that the committee would consider its own inquiry into the matter or he would refer the documents to the Justice Department. Podsiadly was Emmel’s best hope. After he submitted the sensitive information about his employer to the Senate Finance Committee, Emmel signed a non-disclosure agreement with News Corp, and was dismissed from the company the following month. News Corp unleashed a slew of lawyers against Emmel, which eventually forced the man into bankruptcy. As the New York Times has reported, News Corp more or less extinguished allegations of corporate espionage with $655 million in various settlements and buy-outs to competitors. (In-store marketing companies Valassis and Insignia claimed that News Corp had used similar tactics against them.) Podsiadly, as it turned out, may have never opened an inquiry or passed along Emmel’s tip to the Department of Justice.
