Donald Trump's oldest three children plan to remain part of the family business, and youngest daughter Tiffany plans to join in, even if their father wins the White House, but described the political process as being a tough one for the previously non-political family.
"I've been joking for a while that when we started even just this project, we said Trump was coming to Pennsylvania Avenue," daughter Ivanka Trump, 34, told ABC News' George Stephanopoulos during an interview at the new Trump International Hotel, which opened its doors in Washington, D.C. officially on Wednesday.
"We didn't even know at the time what exactly that meant."
But the process has been tough, Donald Trump Jr. admitted.
"It's a brutal process, but that element that's amazing is to be able to touch someone that way and seeing my father doing that," he said. "My only mission is to get him there, because I know he can make a difference."
Ivanka, Donald Jr., and Eric Trump are all senior vice presidents of the Trump Organization, and Ivanka also owns her own fashion line. Tiffany Trump said she just graduated in May, and "of course" she is interested in joining the family business, but in a different way.
"I'm applying to law school, so I'd like to bring a different skill set to the company," Tiffany Trump, the daughter of Trump's second wife Marla Maples, told Stephanopoulos.
Meanwhile, there has been talk that their father's campaign has hindered his real estate development business and Ivanka's fashion line, but they did not agree.
"I think we have the hottest brand and I think the buildings are a testament to what we do every day," Eric Trump said.
Stephanopoulos noted that there is an apartment building in New York where are attempts being made to remove Trump's name, but the GOP nominee, sitting in with wife Melania on the interview with the four adult children, said he thinks the brand is strong.
"It doesn't matter to me," he said. "I don't care. It doesn't matter. I don't care about the brand. I care about the country. "
There have been some attempts to boycott Ivanka Trump's fashion line, but she said she is more interested in talking to the "tens of millions of American women" who are inspired by the brand and the message she'd created.
"My advocacy of women, trying to empower them in all aspects of their life, started long before this presidential campaign did," she said. "I've never politicized that message. People who are seeking to politicize it because they may disagree with the politics of my father, there's nothing I can do to change that."
She pointed out that the Trumps are "not a political family. I think we were attempting to understand real time what that meant in terms of our future and our lives."
