(CNN) - Four sets of anti-war protesters interrupted John McCain in the first 10 minutes of his foreign policy speech Tuesday.
They were all quickly and quietly escorted out. Chants of "John McCain" broke out from the supporters after two of the incidents.
"I have town hall meetings all the time when people are allowed to come and state their views. One thing we don't do is interfere with others' right to free speech," McCain said as one group of protesters were escorted out.
"This may turn into a longer speech than you had anticipated," he joked. "And by the way, I will never surrender in Iraq. Our American troops will come home with victory and with honor."
