Columbus, Indiana -- Outside an Indiana ice cream shop today, Texas Sen. Ted Cruz stepped off his campaign bus and was almost immediately confronted by an angry Donald Trump supporter. Kathy Hiel questioned Cruz about the delegate process, accusing him of rigging the system. The contentious exchange ended with Hiel saying Cruz isn't a natural-born citizen and Cruz saying that if Trump had been confronted by a voter challenging him, the Trump campaign would have threatened the voter with violence.
