A new exhibit, "Americans Now," opened Friday, featuring famous names from science, business, government and the arts.
President Barack Obama and the first lady are among those portrayed. It's the first time Michelle Obama's individual portrait has been shown at the gallery.
Familiar names in the collection also include actor Tom Hanks and music artists Willie Nelson and LL Cool J. Video portraits in the exhibit feature late-night comedians Jay Leno, Conan O'Brien and David Letterman, as well as actor George Clooney and NBA star LeBron James.
The portraits are on view through July 2011.
