The Trump campaign released a statement about this story late Tuesday that said it was "peppered with inaccuracies and omissions," though the statement cited none and the campaign has still not responded to repeated requests for comment.

The New York attorney general's office declined to comment when asked whether its inquiry would cover these new cases of possible self-dealing.

Trump founded his charity in 1987 and for years was its only donor. But in 2006, Trump gave away almost all the money he had donated to the foundation, leaving it with just $4,238 at year's end, according to tax records.

Then, he transformed the Trump Foundation into something rarely seen in the world of philanthropy: a name-branded foundation whose namesake provides none of its money. Trump gave relatively small donations in 2007 and 2008, and afterward: nothing. The foundation's tax records show no donations from Trump since 2009.

Its money has come from other donors, most notably pro-wrestling executives Vince and Linda McMahon, who gave a total of $5 million from 2007 to 2009, tax records show. Trump remains the foundation's president, and he told the IRS in his latest public filings that he works half an hour per week on the charity.
