Four U.S. presidents, including Barack Obama, are scheduled to headline a summit this week that commemorates the signing of a law 50 years ago that brought broad changes in America's social fabric.
The Civil Rights Summit celebrates President Lyndon B. Johnson's signing the Civil Rights Act of 1964.
The event runs Tuesday through Thursday at the LBJ Presidential Library and the LBJ Auditorium on the University of Texas campus in Austin.
Obama will give the keynote address Thursday morning, with former President George W. Bush speaking that evening.
Former President Jimmy Carter will converse Tuesday evening with library director Mark K. Updegrove, and former President Bill Clinton is to speak Wednesday evening.
Panel discussions and other events will include civil rights leaders, current and former officeholders, academics, dignitaries and authors.
NBC 5's Kristi Nelson will anchor the 4 p.m. news live from the summit on Thursday. She will take a closer look at one North Texas community's civil rights struggle.
