New York state's attorney general investigating Trump's charity

WASHINGTON (AP) — New York Attorney General Eric Schneiderman says his office has been investigating Donald Trump's charity to determine whether the foundation has abided by state laws governing nonprofits.

Schneiderman disclosed the investigation in an interview with CNN on Tuesday. Schneiderman said his office has been investigating The Donald J. Trump Foundation over concerns the foundation "may have engaged in some impropriety."

Schneiderman's comments came hours after House Democrats called for a federal criminal investigation of an improper $25,000 donation Trump's charity made in 2013 to a political group supporting Florida Attorney General Pam Bondi after Bondi's office said it was weighing legal action against Trump University.

Schneiderman is a Democrat and has endorsed Hillary Clinton for president.

A Trump campaign spokesman said in a statement that Schneiderman is a "partisan hack" and the investigation is "another left-wing hit job.
