The Trump Foundation has admitted that it had violated a ban on "self-dealing" in a report to the Internal Revenue Service(IRS), local media reported Tuesday.
In its tax filings for 2015, the foundation said it had transferred "income or assets to a disqualified person," which according to regulations, may mean the president-elect, his family members, or his businesses.
The filing was posted online by tracking site Guidestar.
The tax filing also said "self-dealing" was also practiced in previous years.
