'I hope that you wake up': Natalie Harp's estranged brother breaks silence on CNN

The brother of President Donald Trump's devoted aide Natalie Harp spoke out on CNN after she found herself in the spotlight.

During a Tuesday interview, Preston Harp revealed why his estranged sister has latched onto Trump's side and delivered a heartfelt message, saying, "I love you. I hope that you change and that you wake up."

CNN anchor Erin Burnett noted that Harp has drawn more scrutiny after Sen. Jon Ossoff (D-GA) raised questions about her role in the White House, but she also came up in the book Regime Change. Harp also accompanied Trump on his decoy plane to escape an Iranian threat, and new reporting by CNN revealed she even got in the trunk of an SUV to stay close to the president.

"It really blows my mind," Preston Harp said. When Burnett told him about the episode where Natalie Harp rode in the trunk of an SUV to accompany Trump, he laughed, saying, "That's really funny. I didn't even know about that."

"Is it funny?" Burnett asked.

"It's actually kind of sad," Preston said. "That's like an unhealthy obsession."

Natalie Harp credited Trump with saving her life after she beat cancer with the help of experimental drugs that the president supposedly made legal to try.

"What he did was he made experimental drugs legal to try, and that insurance would pay for it," Preston said. "So it's not like he saved her life. It's kind of different."

Explaining their background, Preston Harp revealed, "My mom raised us with the idea that American exceptionalism was the correct way of looking at things. That the United States is the boss of the world, that slavery was, back then, that was normal, people weren't bad because they had slaves."

According to Preston Harp, his sister wrote letters to other presidents, including George W. Bush, even though Natalie Harp claimed, "Politics was never something I liked. Business was my background." None of the presidents to whom she wrote ever responded, but "since she was like 16, she's had an obsession...so, like, her dream came true finally," Preston Harp said.
