What to Know About the Trump Foundation Under Investigation

Who donates, where the money goes and why it's under investigation.

— -- Donald Trump's charitable foundation has come under public and government scrutiny amid recent questions about the source of the nonprofit’s funding and the recipients of its donations.

Keeping It in the Family

The organization's 990 forms for 2001 through 2014 are currently available.

Who Contributes

The biggest contributor from 2011 to 2014 was Richard Ebers, a man associated with an event-ticketing company, Inside Sports and Entertainment, according to the 990 forms.

Ebers was one of two contributors in 2014. The only other contributor that year was a carpet wholesale company, Prestige Mills, based in Long Island in New York, which contributed $20,000 that year and $14,000 in 2011.

All told, Ebers donated more than $1.8 million to the foundation from 2011 to 2014, and he was the largest contributor each of those years.

The number of contributors ranges from as many as six in 2002, 2008, 2012 and 2014 to as few as two in 2001 and 2014.

Donald Trump Sr. made contributions to the foundation from 2001 until 2008, but he is not listed as making any financial contributions since then.

His contributions range from $713,000 in 2004 to $30,000 in 2008; his total contributions to his foundation are in excess of $2.7 million.

Where the Money Goes

A variety of charities are listed as having received contributions from the foundation during those years, some of which have personal ties to Trump and some of which have been mentioned during the 2016 presidential campaign.

Police benevolent societies and athletic leagues, beautification projects, cancer charities like the Dana-Farber Cancer Institute and other medical-research-focused groups like the Michael J. Fox Foundation also received donations from the foundation.

In 2014, the private elementary school that Trump's youngest child, Barron, attended received a $50,000 contribution. In 2007, the foundation gave $500 to a different private school in New York that Donald Trump Jr.’s wife, Vanessa Haydon Trump, attended years earlier. The foundation made at least four gifts totaling $7,200 to the New York Military Academy, where Donald Trump attended high school.

Why It Is Being Investigated

The New York Attorney General's Office has confirmed to ABC News that it is investigating the Trump Foundation.

Schneiderman spoke publicly about the investigation on Tuesday, noting that it wasn't new.

"We’ve inquired into it, and we’ve had correspondence with them. I didn’t make a big deal out of it or hold a press conference. We have been looking into the Trump Foundation to make sure it's complying with the laws governing charities in New York," Schneiderman said on CNN.

The Attorney General's Office shared a letter sent to Donald Trump Sr., dated June 9, 2016, in which it said the Trump Foundation contributed to a political organization, which is against IRS rules.

The letter concerned a $25,000 payment made by the foundation to And Justice for All, a political fundraising group associated with Florida Attorney General Pam Bondi, who this summer spoke at the Republican National Convention and has endorsed Trump’s presidential run.

"In short, the contribution was made in error due to a case of mistaken identity involving organizations with the same name," Weisselberg, the foundation's treasurer, responded in a June 28 letter.

He said in the statement that the foundation "regrets the mistake" and said it "was an isolated incident." He said the foundation learned about the error in March after media reports, at which point it filed appropriate forms with the IRS and Trump paid a federal excise tax with a personal check.

There was further correspondence between the Attorney General's Office and the foundation. One of the letters, sent July 25, from the foundation said Trump who wrote the reimbursement check to his foundation.

The Trump campaign released a statement slamming the investigation as being politically motivated.

"Attorney General Eric Schneiderman is a partisan hack who has turned a blind eye to the Clinton Foundation for years and has endorsed Hillary Clinton for president. This is nothing more than another left-wing hit job designed to distract from crooked Hillary Clinton’s disastrous week," said Jason Miller, the campaign's senior communications adviser.

This isn't the first time that Schneiderman's office has scrutinized a Trump endeavor. The Attorney General's Office launched an investigation into Trump University in 2011 and filed a lawsuit against it and Trump in 2013. Trump has denied Schneiderman's office's allegations regarding Trump University.
