Transcript for Tensions build between Trump, civil rights activist John Lewis
We move on now to the deep tensions between president trump and civil rights activists. That rift heating up over the opening of new civil rights museum in Mississippi. President trump taking a tour of that museum and addressing the crowd. But the president's participation such a flash point that major civil rights figures, like John Lewis, boycotted the event. Here's ABC's David Wright. No hate in our state. Reporter: Today in Jackson, an echo of the civil rights struggle. Hey hey, ho, ho, Donald Trump has got to go! Reporter: A peaceful protest of a president who has fanned racial tensions attending the opening of a new civil rights museum. If you go this way, you see a confederate flag. If you go that way, you will see a confederate flag. Now how are these men who are standing up talking about civil rights right now, how are they squaring that message with all these confederate flags that are all over the place? It really is a beautiful, beautiful place. Reporter: Trump's message today, one of inclusion. These buildings embody the hope that has lived in the hearts of every American for generations. Reporter: Because trump was there, civil rights legend John Lewis was not. Congressman Lewis, one of the heroes of bloody Sunday in Selma, called president trump's attendance, an insult to the people portrayed in this civil rights museum. Four months ago, there was this scene in charlottesville, and trump's carefully measured response. We condemn in the strongest possible terms this egregious display of hatred, bigotry and violence on many sides. On many sides. Reporter: Just last night, at a rally in Pensacola -- Blacks for trump. I love you. Reporter: Trump pledged his suppt for Alabama senate candidate, Roy Moore. Trump and Lewis have feuded all year. Trump tweeting in January that Lewis is, all talk, talk, talk. No action or results. Sad. This weekend, Lewis plans to campaign in Alabama for Moore's democratic opponent. In Jackson today, trump supporters gave him credit for coming. Those of us supporting him are trying to do the right thing. Nobody's perfect, but at least he is trying. And David Wright is with the president in west palm beach tonight. David, let's go back to that race. Late word that president trump has recorded a robo-call in support of Roy Moore? Reporter: That's right. These are those phone calls dialed by a computer that are landing during the dinner hour. Such a big part of get out the vote operations these days. The white house confirms tonight that the president did record a call for Moore. The Moore campaign tells ABC news they plan to roll it out statewide tomorrow. David right for us tonight. David, thank you.
