"[Clinton is] actually an appendage of the military-industrial complex," Lange said on Wednesday. "Her foreign policy is nothing but more and more war."
He explained that Clinton’s advocacy for military intervention was responsible for the deaths of thousands of people in Libya.
Lange, a delegate from the US state of Ohio, noted that Sanders was the only candidate for either party who advocated reducing the budget of the US military and focusing on domestic priorities.
"We’ve got to get out of the Cold War mentality. We’ve got to get out of being on the brink of nuclear war," Lange explained.
Earlier on Wednesday, Clinton advisor James Rubin said Washington should play a bigger role in Europe and had become too disengaged from world affairs under President Barack Obama’s administration.
