in 1999, playwright and activist larry kramer claimed that he had uncovered previously unknown documents while conducting research for his work-in-progress, "the american people: a history". some were allegedly found hidden in the floorboards of the old store once shared by lincoln and joshua speed. the documents reportedly provide explicit details of a relationship between lincoln and speed, and currently reside in a private collection in davenport, iowa. their authenticity, however, has been called into question by historians such as gabor boritt, who wrote, "almost certainly this is a hoax." c. a. tripp also expressed his skepticism over kramer's discovery, writing, "seeing is believing, should that diary ever show up; the passages claimed for it have not the slightest lincolnian ring."
