FRANKFORT — The former director of the state Legislative Research Commission says he returned to his office over the weekend and shredded paperwork.Robert Sherman toldThe Courier-Journal that the documents included "personalized stuff" such as old salary comparisons. He said none of the paperwork involved anything to do with the sexual harassment allegations involving a former lawmaker or any investigations the agency is involved in.Sherman's actions have raised concerns among lawmakers, who say he should have gotten permission before destroying the documents and allowed some independent oversight.Sherman said others, including Deputy LRC Director Robert Jenkins, were present when the documents were shredded.Jenkins said only extra copies of paperwork that were in Sherman's office were shredded as it was cleaned out. He said all the documents are in other LRC files.
