It’s been 50 years since the Civil Rights Act became part of the fabric of America. This week, the LBJ Library is honoring Lyndon B. Johnson’s legacy in Austin with a three-day summit on the past, present and future of civil rights.

In Tuesday’s Capital Tonight, we took an in-depth look at how the law has rippled through history, plus we spoke to some of the lawmakers dealing with similar issues today.

THEN AND NOW

Former Texas Lt. Gov. Ben Barnes was one of many lawmakers who helped transition the state away from laws based on racial discrimination, all in the years during and after LBJ’s presidency. We sat down for an extended interview with Barnes about segregation, civil rights and his role in this week’s summit.

POLITICS OF TODAY

Same-sex marriage is seen by many as a key civil rights issue today. We heard from two lawyers from very different political backgrounds who came together over marriage equality.

Plus, we spoke to political strategists Harold Cook and Ted Delisi about the same-sex marriage debate and more.
