I couldn't post the hard copy of Feinstein's response to an email I sent regarding Calderon's call for the U.S. to give up its sovereignty. She basically disagreed with his views but defended Calderon's "rights to comment on U.S. policies that may affect his country". She sugeested I contact Calderon's office directly to express my concerns at: http://contacto.presidencia.gob.mx/en/
I wrote him an email four days ago, no word yet.
