New York Attorney General Eric Schneiderman is making inquiries into the Donald J. Trump Foundation, a source told CNBC, after Schneiderman told CNN of concerns that the presidential nominee's charitable foundation may have been involved in "some impropriety."

Schneiderman told CNN's "The Lead" on Tuesday that he was "looking into the Trump Foundation and making sure it's complying with the laws that govern charities in New York."



"My interest in this issue really is in my capacity as regulator of non-profits in New York state and we have been concerned that the Trump foundation may have engaged in some impropriety from that point of view," Schneiderman said.

The Attorney General, who has also been embroiled in an alleged fraud case against Trump University, told CNN that his office had "inquired into" the issue and exchanged correspondence with the foundation but "didn't make a big deal out of it or hold a press conference."

The inquiry comes on the heels of a report in The Washington Post that the GOP presidential nominee had not donated to his foundation since 2008. Schneiderman has previously endorsed Democratic nominee Hillary Clinton.

Trump campaign spokesman Jason Miller called Schneiderman's comments as "nothing more than another left-wing hit job designed to distract from Crooked Hillary Clinton's disastrous week."

"Attorney General Eric Schneiderman is a partisan hack who has turned a blind eye to the Clinton Foundation for years," Miller said.
