WASHINGTON (AP) -- Congressman John Sullivan of Tulsa is sending a letter to Mexico's president in which he calls Mexican immigration policy "blatantly hypocritical."

Sullivan says in the letter to President Vicente Fox that while Fox calls US efforts to enforce immigration laws discriminatory -- Mexican laws deny basic human rights to immigrants in that country.

The letter also says Mexican immigration restrictions are the least humane on the continent. And he calls on Fox to stop criticizing US immigration policies while Congress is considering immigration reform legislation.

A spokesman at the Mexican embassy in Washington says the letter has not been received and said he could not respond to it.
