MARGARET BRENNAN: As for the former president, his Friday night remarks at the Black Conservative Federation gala in Columbia, South Carolina, continued to overshadow his victory.
DONALD TRUMP: Black conservatives understand better than most that some of the greatest evils in our nation's history have come from corrupt systems that try to target and subjugate others to deny them their freedom and deny them their rights. You understand that. I think that's why the black people are so much on my side now because they see what's happening to me, happens to them. These lights are so bright in my eyes that I can't see too many people out there, but- I can only see the black ones. I can't see any white ones you see, that's how far I've come.
BRENNAN: We begin with CBS News Chief Election and Campaign Correspondent Robert Costa who joins us from Charleston. Bob, this was an open primary in South Carolina, but just 3% of voters were black. Do Donald Trump's remarks about black Americans give the party any pause here?
ROBERT COSTA: It's giving Nikki Haley a road ahead at this point, Margaret. She and her campaign believe there are many traditional Republicans across the country who are fed up, not only with former President Trump's legal problems, but his incendiary comments on race, and they believe that they- that could ostracize key voters across the country come November. That's why she's staying in right now, going to Michigan this week for that primary, staying in through super Tuesday. But there is real worry that as Trump takes over the party and the Republican National Committee, there’s no reckoning about how he’s handling issues like race and immigration.
