New giant pandas on way to National Zoo

The Smithsonian's National Zoo welcomed two new giant pandas on Tuesday. Bao Li (precious vigor) and Qing Bao (green treasure) started their long journey from China to Washington, D.C. on Monday. Their arrival will come 11-months after the Zoo returned the wildly popular pandas Mei Xiang, Tian Tian, and their cub Xiao Qi Ji.
