ET's Mary Hart was invited inside the White House for the Bush family's last Christmas in office -- and First Lady Laura Bush is leading a tour of the house's holiday decor.

The First Lady takes Mary into the blue room where this year's tree is a stunning Fraser fir from North Carolina. The theme: red, white and blue Christmas. This year each member of the United States Congress was asked to choose an artist to decorate an ornament for the White House Christmas Tree that would best represent their district.

This is the Bush's eighth and final Christmas at the Presidential residence. Watch the video to see the tree and more of the White House all dressed up for the holidays!
