When Donald Trump announced his run for president last June, he also managed to promote his book, his real estate and his golf courses, which he said are "some of the best in the world."
If he becomes president, Trump would continue to have the ability to own and promote his multitude of businesses — even though some of those business interests are politically sensitive.
Ethics lawyers and presidential law experts say that despite a thicket of rules governing business interests in the executive branch, there is no rule that would prevent Trump from owning or promoting The Trump Organization if he's elected.
While Trump has said he might turn over day-to-day management to his children, he has not ruled out retaining his ownership stake or board seats in his multibillion-dollar global brand empire.
"There's really nothing in the law to prevent him from keeping his business," said Kenneth Gross, a partner at Skadden, Arps, Slate, Meagher & Flom who has advised several wealthy presidential candidates, Cabinet members and presidential appointees on navigating the ethics rules. "He would have to walk a very fine line and he [would] constantly have to be concerned about these issues. But he could keep it."
A spokeswoman for Trump's campaign did not return CNBC's calls or emails for comment. But Trump's campaign manager, Corey Lewandowski, told The Associated Press in January that "Running the country is clearly what Mr. Trump wants to do."
"Should he have the privilege of being elected president, he will be spending 110 percent of his time on that," Lewandowski told the AP.
