Fellow readers whose interests are piqued by this comment: this is apparently true. This book [1] talks about it in greater depth. From Wikipedia:
> [The author] describes the growth of the Abstract Expressionist art movement, and its frequent showcasing in New York's Museum of Modern Art (MOMA), as largely a CIA-sponsored operation [...] Since many abstract expressionist painters and sculptors were anarchistic, and strongly anti-CIA, a "long leash" policy was adopted that "kept CIA operatives at a remove of two or three degrees from the artists and art exhibitions—sometimes even more—so that they could not be linked to any furtive governmental bankrolling."
