The Trump administration says left-wing terrorism in the US is on the rise. Is it?

For many years, the far right has been the most lethal and persistent source of domestic terrorism in the U.S. But the assassination of right-wing influencer Charlie Kirk last month and attacks against immigration enforcement efforts have fueled a talking point for Republicans about concerns over left-wing political violence. The political motivations behind these attacks are still unclear, but one study says that violence from the left has been the greater threat so far this year. NPR’s domestic extremism correspondent Odette Yousef looks into whether this claim is correct.
