The Trump family is learning how to navigate the line between politics and business. Donald Trump has chosen to retain his stake in his company, which means that the president stands to personally benefit from any gains made by the company through new ventures, partnerships, and expansion. And expansion is just what the Trump sons plan to do next.

Donald Trump, Jr. told The Washington Post that he and his brother Eric were inspired by many places they visited while with their father on the campaign trail. While Trump has not divested from his company, he’s turned over management of the Trump brand to his sons. The plan now is to build new properties, starting with a more affordable chain of hotels, Scion, in a number of cities across the nation, many of which the brothers became acquainted with while on the long road to the White House.

“I got to see a lot of those markets on the campaign,” Donald Jr. said. “I think I’ve probably been in all of them over the last 18 months.” The Scion project is set to begin new buildings in cities like Austin, Dallas, St. Louis, Nashville and Seattle — cities in which the Trumps met many potential development partners over the course of the campaign.

“I met people along the way that would be awesome partners,” Donald Jr. said.

Donald Trump has been particularly criticized for his involvement in the family business — even though he’s remained laissez-faire thus far, in accordance with the rules of office, he stands to gain as much from successful new ventures as the rest of his family does. The Post outlines a number of conflicts of interest the White House could face while remaining connected to Donald Jr. and Eric’s businesses:

Building new hotels, for example, could create issues — tax disputes, allegations of labor violations or environmental violations — that require federal departments to consider cases that could directly impact the president’s finances. And while the Trumps have vowed to sign no new foreign deals, pursuing a raft of new domestic contracts from coast to coast means the Trumps are likely to engage in negotiations with private developers, banks and investors who see additional benefits in doing business with the president’s company.

Scott Amey, a member of the watchdog group Project on Government Oversight told the Post, “It’s just going to add fuel to the fire that is already burning . . . with him having still a foot in both the boardroom and one in the Oval Office.”

“There are lines that we would never cross, and that’s mixing business with anything government,” Eric Trump said.
