As the National Portrait Gallery works on its latest commission -- an official portrait of former President Donald Trump -- we take a spin through the ‘America’s Presidents’ exhibition. This episode draws back the curtain on earlier commissions that have drawn controversy and acclaim: a portrait of Bill Clinton with a shadow of scandal painted into it, and the Obama portraits that transformed the museum into a pilgrimage site. Director Kim Sajet also digs into the thorny question of what a presidential portrait is meant to convey, especially if the president in question has been impeached. Should it carry the glow of prestige, or the markers of personal failings? Is this gallery hallowed ground, or a place to question power? "If you're in the business of showing these paintings," says Washington Post art critic Philip Kennicott, "you want to send people out a little hungry." Also featuring former deputy director Carolyn Carr. See the portraits we discuss here: President James Buchanan President Richard Nixon President George H. W.
