Texas Republican Sen. John Cornyn talks to reporters following the address of Felipe Calderón Hinojosa, President of Mexico in Washington DC. on May 20, 2010. Cornyn said it was inappropriate for Calderon to lecture Americans on state and local law. He defended the Arizona law and added: "moreover, the Second Amendment is not a subject open for diplomatic negotiation, with Mexico or any other nation." Calderon, the first foreign national leader to address Congress this year, said he strongly disagrees with the Arizona law that requires police to question people about their immigration status if there's reason to suspect they are in the country illegally. He said there are more than 7,000 gun shops along the border where almost anyone can purchase weapons. (Photo by Jeff Malet)
