In 1926, Houdini testifies before the US Congress in favor of legislation that would regulate psychics, mind readers and mediums. He then posts an open call to all mediums offering to donate $10,000 to charity - over $150,000 in today's money. If they can bring him a supernatural act that he can't figure out, but no one ever does,. It's later described as quote, for raucous days, order in the chamber, disintegrated police were repeatedly summoned and the husband of a medium nearly punched Houdini in the face.
