Rand Paul sharply criticized fellow Senate Republican Lindsey Graham for suggesting that U.S. troops should remain in northern Syria.

“Lindsey Graham has been wrong about almost every foreign policy decision of the last two decades,” the Kentucky senator said during a Tuesday morning appearance on MSNBC. “He was wrong about the Iraq War. The Iraq War was a mistake. It made Iran stronger, allowed more chaos, more instability, and more terrorism. He was wrong about the war in Libya. It lead to more chaos and more terrorism. He is wrong about this.”
