Former St. Paul Pioneer Press publisher Par Ridder now admits he took confidential information from his old employer to his new job as publisher of the Star Tribune of Minneapolis. In videotaped testimony played today in a Minneapolis courtroom, the son of former Knight Ridder CEO and chairman Tony Ridder acknowledged copying confidential financial documents from his Pioneer Press computer onto a portable computer drive and taking them to the Star Tribune, according to the Associated Press. He also acknowledged sharing some of that data on advertising, profits and personnel matters with Star Tribune officials, including members of its operating committee. Dean Singleton, who operates the Pioneer Press and controls most of the newspapers in the Bay Area, was sitting in the courtroom when the testimony was played. Singleton is suing Ridder.
