A woman looks at a section of the "Americans" exhibit that explores the historical context of the Trail of Tears, at the Smithsonian's National Museum of the American Indian, Friday, Feb. 9, 2018, in Washington. A new exhibit uses images of Natives to show how the population permeates American culture. The "Americans" exhibit has received good reviews, but some say the accompanying website falls short in its characterization of an 1830 U.S. law that forced thousands of American Indians off their lands.
