Throughout American history, the annual celebration of family and gratitude known as Thanksgiving has been a central part of The White House and the U.S. presidency.

This week, President Barack Obama kept the tradition alive by pardoning Cobbler, the National Thanksgiving Turkey, in a Rose Garden ceremony. His feathered understudy, Gobbler, was also allowed to live, and both birds will live out the rest of their days on display at George Washington’s Mount Vernon Estate and Gardens in Virginia.
