Wall Street Journal report:

…as the inquiry unfolds, more attention is beginning to focus on former House clerk Jeff Trandahl, who both oversaw the page program and was close to Mr. Foley. Mr. Trandahl, who left his House post last November, has declined any comment on his role. But from interviews with colleagues, he emerges as both an adviser and friend to Mr. Foley.
Kirk Fordham, Mr. Foley’s chief of staff until late 2003, has said warnings from Mr. Trandahl about Mr. Foley’s conduct were what led him to ask the speaker’s office to intervene with the congressman more than two years ago. And last fall, Mr. Trandahl again played a central role when he was dispatched with Rep. John Shimkus (R., Ill.) the chairman of the page board, to warn Mr. Foley against any further emails to a former page from Louisiana…
…But Mr. Trandahl was in a unique position to recognize the implicit danger in the fact that Mr. Foley wasn’t just close to pages on the House floor but was pursuing contact via email. And fellow Republicans say House staff could have done more then to warn Mr. Hastert and other House leaders of the potential danger.
