(CNN/CBS) - The President is usually greeted in a city by handshakes and pleasantries, but not this time. President Obama had an unusual moment with Arizona republican governor Jan Brewer.
She and President Obama had an intense encounter as the president was getting ready to board his motorcade. Pool reporters noticed the two were interrupting each other and at one point, the governor was pointing her finger at the president as she spoke.
