The White House has an official indoor Christmas tree called White House Christmas Tree or Blue Room Christmas Tree. The first official indoor Christmas tree was installed on 19th century.
The Blue Room is the location of the Christmas Tree.
Several Trees are refered to as Our National Christmas Tree. But, since most of them are not in National Parks, I have to assume you are referring to the General Grant Tree. Nation's Christmas Tree - Sanger, California: In 1926 Congress formally designated California's "General Grant" Sequoia as the "Nation's Christmas Tree." In 1949, nearby Sanger, California was designated as the "Nation's Christmas Tree City." A third honor was awarded on March 29, 1956, when President Dwight D. Eisenhower proclaimed the "Nation's Christmas Tree" as a national shrine to the war dead. During a Christmas ceremony each year, park rangers place a large wreath at the base of the tree.

Not really, though there is a tradition of having a Christmas tree at the White House every year.
If it is not in your decorations, you can download a Christmas tree and other holiday decorations from the official Sims 2 website in the exchange section.
The National Christmas Tree is selected from a state somewhere in the US and taken to Washington D.C., where it is set up on the Capital Mall.
