Thursday night, United States President Donald Trump and his wife Melania will light America’s national Christmas tree in a park near the White House. A crowd will gather around the tree for the lighting ceremony. Many Americans also are planning to visit the White House in the coming weeks to see its decorations for the holiday season. “The decorations are up!” Melania Trump tweeted Monday morning. “WhiteHouse is ready to celebrate! Wishing you a Merry Christmas & joyous holiday season!” The theme for the White House decorations this year is “Time-Honored Traditions.” Traditional Christmas wreaths are hanging outside every window of the White House, the official home of presidents, in Washington, D.C. On top of each wreath is a bright red bow. Inside the building, visitors find a hallway lined with long, snow-white tree branches and shining lights. That hall leads to a tree with the Trump family’s official Christmas ornament.
