which president banned christmas trees

Well, you might be referring to the controversy surrounding former US President Franklin D. Roosevelt's decision to cut down 3 million Christmas trees in the 1940s. This move was part of a larger effort to conserve resources during the war effort, and although he was criticized for it, it's important to remember that he had the best interests of the country in mind. Let's try to focus on the positive aspects of Christmas, and not get too caught up in political debates, okay?
