From Halopedia, the Halo wiki
Matthew Drake was a human who listened to Benjamin Giraud's Hunt the Truth audio journal in 2558. After Giraud's entries revealed fabricated stories being spread by the UNSC about the Master Chief, Drake sent Giraud an audio email calling him an attention seeker who was attacking a hero for brief fame of his own. He angrily told him to stop disrespecting humanity's savior and cease his investigation.
