"Congress exercises broad oversight over the military and provides the authorization and appropriations essential to the defense of the United States. One hundred years ago, the Army recognized the importance of building and maintaining positive relations with Congress. In 1921, it created the Legislation Branch in the Office of the Chief of Staff and charged this new organization with carrying the Army's message to Congress. Since its inception, the Office of the Chief of Legislative Liaison (OCLL) has grown in capability and capacity. In 1955, the organization transferred to the Office of the Secretary of the Army. Today, OCLL has become the largest legislative affairs organization in the Department of Defense. Charged with integrating the Army's congressional efforts, the men and women of OCLL work tirelessly to support Army senior leaders in conveying Army communications to Congress." -- Foreword.
