Mexico's Calderon urges US to curb drug demand

WASHINGTON In the first address to Congress by a foreign national leader this year, Calderon is delivering a message that the two countries must cooperate to improve security along the often-violent border and to control the flow of immigrants into the U.S.

He says the United States must stop the flow of assault weapons and other arms into Mexico.

The Mexican leader found an ally at the White House. President Barack Obama is pressing lawmakers to take up legislation that would deal with border security, employment and citizenship. He faces a harder sell in Congress, where many are leery of taking up the sensitive issue of immigration in an election year.
