A few dozen immigrant rights activists chanted "Boycott Arizona" outside Wrigley Field in Chicago as the Cubs opened a four-game series against the Arizona Diamondbacks.

Protesters are upset over Arizona's new immigration law that makes it a crime to be in the U.S. illegally.

Activists nationwide have called for a boycott of Arizona tourism and of state businesses.
