MARY LOUISE KELLY, HOST:
Law enforcement and people who live here in D.C. are bracing again for the possibility of extremist violence on Capitol grounds. A rally called Justice for J6 is set for tomorrow - J6 a nod January 6, when a mob of Trump supporters launched an attack on the Capitol building. NPR's Odette Yousef covers domestic extremism and is here now.
ODETTE YOUSEF, BYLINE: Hey, Mary Louise.
KELLY: So tell us a little bit more about this rally. Who's expected to go and what's the message?
