The White House Christmas decorations are typically funded by the White House Historical Association, a non-profit organization that is responsible for preserving and promoting the history of the White House. The association covers the cost of the decorations and manages the installation process, working closely with the First Lady's office to ensure that the decorations reflect the spirit and traditions of the holiday season. The association's support is important in maintaining the tradition of decorating the White House for Christmas, which dates back to the 1800s.
