Writer Stephen Glass had been a major contributor under Kelly's editorship; Glass was later shown to have fabricated numerous stories, and falsified his notes and other backup materials. "The New Republic" issued a public apology for this breach of journalism ethics after it was revealed by an investigation by Kelly's successor, Charles Lane. "Forbes Online" had published an exposé of Glass' work. Kelly was Glass's editor before "Forbes" exposed the latter's falsehoods. He was largely supportive of Glass, sending scathing letters to those who challenged the veracity of Glass's stories.
