The official, national Christmas tree arrived at the White House over the weekend -- an ongoing tradition the day after Thanksgiving.  The tree arrived on a horse-drawn wagon Friday morning (for inspection of course) and was greeted by first lady Michelle Obama, the first family's two dogs and of course, daughters Malia and Sasha.

The national tree is a 20-foot white fir and is from a farm run by Chris Botek, a second-generation Christmas tree farmer.  Botek also provided the official White House tree back in 2006 and 2010.

The tree is chosen weeks in advance and "crowned" through the National Christmas Tree Association contest. Then the winner presents the tree as the official White House tree -- a tradition since 1966.
