Rev. Franklin Graham, the influential evangelist preacher who is scheduled to speak at the convention Thursday night, talked with ABC News Live hours before he is set to take the stage.
Graham spoke about Trump's changed stance on abortion that would leave the matter up to the states.
"President Trump ... has a very difficult position because he has to represent all Americans and that includes people who have different views," said Graham, who is publicly anti-abortion.
"I believe President Trump had Roe v. Wade defeated," Graham added. "No other president has been able to do that."
When asked about his support for Trump after he became a convicted felon, his ties to a porn star or his offensive remarks, Graham responded, "Donald J. Trump has made many mistakes in his life, and I'm sure he regrets, many of them ... all of them."
"But at the same time, I look at his policies and what they do for America … and so I believe that Donald J. Trump can ... help get this country's economy back," he added.
Graham is the son of influential evangelist Billy Graham, who died in 2018.
