This Saturday August 15th, people in cities from Chicago to Perth, Australia will gather to show their support of the Iranian nuclear deal. The event began as a small idea with a group of young Iranian Americans who wanted to do something to help garner support for a deal they say will lead to a more peaceful world. The grassroots campaign has now reached more than 70 cities with different events planned across the globe this Saturday. Negar Mortazavi, one of the principal organizers of the global campaign Support Iran Deal, joins us to discuss the movement and what they hope to accomplish. (Photo by Negar Mortazavi_
