Louisville is hosting the inaugural Define American Summit this weekend, welcoming hundreds of visitors to comedy shows, work shops and discussions about race, culture and identity. It all aligns with the nonprofit Define American's mission to share stories and stir change around immigration, identity and citizenship. This week on WFPL's In Conversation, we talk with officials and guests taking part in the summit to ask how they define 'American' and how they use their stories to make change. Our guests were Comedian Nikita Hamilton, Define American Executive Director Ryan Eller, Comedian Zahra Noorbakhsh and Actor Christian Arteaga.
