what president banned christmas trees in the white house

The answer to your question is President Calvin Coolidge. In 1923, he banned Christmas trees from the White House, as he believed it was too big and took up too much space. Instead, he had a small tree placed on the President's desk in the Oval Office. This decision was met with criticism and was quickly reversed by his successor, Herbert Hoover, who reinstated the tradition of having a large Christmas tree in the White House.
