“Politician” is using a bit of license, but the reference is to Jesus discovering the temple in Jerusalem was being used as a market. John 2 is the only account that includes a whip:

When it was almost time for the Jewish Passover, Jesus went up to Jerusalem. In the temple courts he found people selling cattle, sheep and doves, and others sitting at tables exchanging money. So he made a whip out of cords, and drove all from the temple courts, both sheep and cattle; he scattered the coins of the money changers and overturned their tables. To those who sold doves he said, “Get these out of here! Stop turning my Father’s house into a market!”
