Did lady bird Johnson have Vietnam business interest?

Lady Bird Johnson did not have any known business interests related to Vietnam during her time as First Lady of the United States. She focused on environmental conservation and beautification efforts, such as the Highway Beautification Act and the creation of the First Lady's Committee for a More Beautiful Capital. While her husband, President Lyndon B. Johnson, was heavily involved in the Vietnam War, there is no evidence to suggest that Lady Bird Johnson had any personal business interests in the region.
