A new NBC-Wall Street Journal poll out Monday showed retired neurosurgeon Carson grabbing the front-runner spot in the race for the Republican nomination, garnering 29 percent of Republican voters to Trump's 23 percent.
Trump also talked about his personal life during the interview, reflecting on his career and his family. "My work has always been all-encompassing," he said, but went on to say that he also prioritized his children.
"I think [my kids] would say I’ve been a really good father," he said. "I could be in the biggest deal, and if they call, I’m always there for them."
As for the Republican side, he said, “I think I will be the nominee.”
