Reorganization
In 1954, during the Eisenhower administration, the WHSD was reorganized under the Office of the Chief Signal Officer, Army Signal Corps as a Class II unit and renamed the White House Army Signal Agency (WHASA). In 1962 WHASA was discontinued by order of the United States Secretary of Defense under President John F. Kennedy. Its duties were transferred to the auspices of the Defense Communications Agency under the operational control of the White House Military Office, and reestablished as the White House Communications Agency.
