A joint session for the President of Mexico?

Congress has hit a new low as Mexican President Felipe Calderon addressed a joint session on may 20th to enlighten the American People about how to improve our immigration policies. What a sham, if I were the Republicans I would of gotten up and walked out or not even have attended. I mean seriously, what right other than being a head of state, does he have to go before congress and give his two cents about U.S. policy. I'm disgusted by what our government has become and hope that upcoming elections can give the country some clarity.
