Marshall Fields (White House intruder)

Marshall Fields was involved in a 1974 Christmas Day intrusion into the grounds of the White House complex. Although he eventually surrendered, Fields threatened White House security during negotiations that lasted for four hours. Along with an intrusion by Robert K. Preston in February of the same year, this incident sparked a security review by the U.S. Secret Service.
