Scott Hagerstrom, a worker for the Koch-backed Tea Party group Americans For Prosperity, appeared on Hardball on MSNBC to talk about the right-to-work protests in Michigan, and Chris Matthews let him have it over the group's ties to the billionaire conservatives.

“This is pretty much a union-gutting operation,” Matthews said about the state's legislation. “You work for the Koch brothers. They don’t like unions. Why are you working for them?" Hagerstrom replied: “I work for Americans for Prosperity. This is not about the Koch Brothers.”

Matthews fired back: “Who’s paying your salary?" Hagerstrom kept repeating: “I work Americans for Prosperity."

"What’s that?" Matthews asked.
