Andrew Giuliani, the 21-year-old son of Rudy Giuliani, has some questions about pappy’s moral values. The Duke University student has told ABC News that he doesn’t want to hurt his father by speaking frankly in the press, but he’s also not about to keep quiet. His negative feelings largely center on Rudy’s treatment of his family after his messy divorce from Donna Hanover and marriage to Judith Nathan:

“We are both working on our relationship,” Andrew Giuliani told ABC News. “No matter what he’s done, I love my father. He’s my father and we love each other. It’s not as good as it once was — but it’s better than when it was its lowest, and it is getting better all the time.”

“This is something families around the country go through every day,” he added. “My friends go through this. But this is front-page news because of who we are.”

Andrew Giuliani made clear that despite their personal differences, he fully supports his father’s bid for president, and believes he’s the right person to run the country.

“I have problems with my father, but it doesn’t mean he won’t make a great president,” he said. “He was a great mayor. He did great things for New York and would be very effective as a president. He is a great leader. He has vision, and he is willing to stand up for what he believes in.”

Andrew added that he does not plan on participating in his dad’s run for president. “I will not be active in his campaign,” he said. “I am too busy with golf.”
