I love this show the things I have learned is amazing. But it is very often that I find a mistake. I was watching the episode about Teddy Roosevelt son and the first Christmas tree in the White House. That was not the first time a Christmas in the White House. President Benjamin Harrison had one in 1889. On the second floor it was decorated with candles, toys, and other ornaments designed to impress the Harrison grandchildren. But I still learn a lot watching this show.
