It is a choir of two, singing for millions. “She says their names,” Morgan Freeman intones, and Hillary Clinton’s voice, clipped from the campaign trail, seems to blend in with his: “Trayvon Martin,” they both say. “Shot to death,” says Mrs. Clinton, as pictures of victims of police brutality, and their grieving mourners, flash on screen. Dontre Hamilton: “Unarmed,” she says. “Sandra Bland did nothing wrong,” she says. Mr. Freeman drives home the point: Mrs. Clinton “makes their mothers’ fight for justice her own.”

As we follow Mrs. Clinton to Flint, Mich., Mr. Freeman continues: “She speaks for a city poisoned by indifference.” Speaking from the pulpit of a black church there, she demands: “We need action now.”

Finally, photos show Mrs. Clinton alongside President Obama, looking on proudly by his side as he speaks, and meeting privately with him in the Oval Office, as Mr. Freeman assures viewers that she “stands with the president against those who would undo his achievements — just like she’s always stood with us.”

Message

Mrs. Clinton as defender, protector and champion of African-Americans: children, families, cities, even a victimized president.
