Sen. Bernie Sanders took issue Sunday with the Clinton Foundation for taking millions of dollars from Saudi Arabia and other governments that oppress civil rights and civil liberties while Hillary Clinton was secretary of state.

Sanders told CNN's "State of the Union" that he does in fact "have a problem" with the Clinton Foundation taking those sums of dollars from those types of governments. Between the foundation's inception in 2001 and 2014, Saudi Arabia gave the foundation between $10 million and $25 million.

"Yes it is [a problem]," Sanders said. "You asked me about the Clinton Foundation. Do I have a problem when a sitting secretary of state and a foundation run by her husband collects many millions of dollars from foreign governments, governments which are dictatorships? You don't have a lot of civil liberties, democratic rights in Saudi Arabia. You don't have a lot of respect there for divergent, opposition points of view, for gay rights, for women's rights. Yeah — do I have a problem with that? Yeah, I do."

Sanders also told host Jake Tapper that the situation does indeed create the appearance of a conflict of interest.

The Clinton Foundation has long defended their practice of taking money from foreign governments.
