From the Washington Post today:
It was not clear what allegations the board was concerned about. But The Washington Post has learned of a potentially inappropriate incident involving Kolbe and a male page. The man recently told the House clerk’s office and the FBI about an encounter with the Arizona Republican that occurred about five years ago when he was 16, according to someone familiar with the man’s account. The page told authorities that he was “uncomfortable with a particular social encounter” that involved physical contact when he and Kolbe were alone, the source said yesterday.
