As the impeachment trial of Donald Trump proceeds, we speak with two historians about the importance of accountability for the January 6 insurrection and white supremacist attacks in the United States. The scenes of violence at the U.S. Capitol were “familiar” to Black people, says Ibram X. Kendi, author, professor and founding director of the Boston University Center for Antiracist Research. “We have consistently, over the course of 400 years, faced white supremacist mob violence.” We also speak with Keisha Blain, an author and associate professor of history at the University of Pittsburgh, who says Trump must be held accountable for inciting the Capitol insurrection. “We cannot hold back and play games here,” she says. “Whatever decision we make in this moment will determine the future of this nation.”
