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.
