Republican presidential hopeful Scott Walker confronted a protester at the Iowa State Fair on Monday, standing tall against the heckler while giving a soapbox speech.
According to CNN, dozens of protesters interrupted the Wisconsin governor's remarks with boos and chants of "liar." Eventually, Walker called out one protester.
"I am not intimidated by you, sir, or anyone else out there," Walker said. "I will fight for the American people over and over and over and over again."
