Democratic presidential candidate Hillary Clinton responded in an interview aired Sunday to Sen. Bernie Sanders (I-VT)’s campaign manager suggesting that she is to blame for the rise of the Islamic State, calling his comments “beyond absurd.”

Jeff Weaver, Sanders’ campaign manager, said last week that Clinton has a “hawkish” stance on foreign policy that “has led to the rise and expansion of ISIS throughout the Middle East.”

Clinton was asked to respond to the comments on CNN’s “State of the Union.”

“Well, that is beyond absurd. You know, they’re saying a lot of things these days, and I’m just going to let them say whatever they choose to say,” Clinton said. “But, you know, ISIS was primarily the result of the vacuum in Syria caused by Assad, first and foremost, aided and abetted by Iran and Russia. So I think that let’s put responsibility where it belongs.”
