Donald Trump's son told CNBC on Wednesday the latest revelations about the Clinton Foundation proves "pay to play" and "corruption at the highest level."
"It should not be happening. It makes the whole world question our system. We are leaders of the free world. Why are we doing it?" Eric Trump said in an interview on "Squawk Box."
The Clinton campaign did not immediately respond to a CNBC request for comment.
Newly released emails from Hillary Clinton's time as secretary of state showed Clinton Foundation donors sought, and sometimes received, access to her and her State Department aides.
An Associated Press report indicated more than half of the private interests who met with Clinton during her time leading the State Department were donors to the Clinton Foundation.
Clinton's campaign vigorously pushed back in a statement Tuesday night, objecting to the AP conclusions and methodology.
Donald Trump, in a rally Tuesday in Texas, accused Hillary Clinton and former President Bill Clinton of setting up a "business to profit from public office."
Eric Trump is involved in his own charity.
In 2006, he founded The Eric Trump Foundation to benefit St. Jude Children's Research Hospital. The foundation has donated and pledged nearly $30 million to pediatric cancer research and treatment, according to the Trump Organization website.
He's also executive vice president of development and acquisitions for the Trump Organization.
