Mitchell to Joaquin Castro: You’re Cuban American; Castro: I’m Mexican-American

MITCHELL: "And joining me now here in Panama City, Congressman Joaquin Castro, a member of the House Foreign Affairs Committee. Thanks very much, we'll talk politics but I want to talk about the reason we're here, this Latin American summit, the first one attended by Cuba because of the change in U.S. policy. You have a Cuban-American background." 
CASTRO: "I'm Mexican-American, but the same last name --" 
MITCHELL: "Mexican-American, but you understand the real divisions in the Hispanic and Latino communities about this."
