A protester shouts as he joins thousands attending an immigration rally at the Arizona Capitol on Sunday, April, 25, 2010.
Activists called on President Barack Obama to fight a tough new Arizona law targeting illegal immigrants, promising Sunday to march in the streets and invite arrest by refusing to comply if the measure goes into effect.
U.S. Rep. Raul Grijalva of Arizona told about 3,500 protesters gathered at the state Capitol that the Obama administration can help defeat the law by refusing to cooperate. The law requires Arizona police officers to question people about their immigration status if there is reasonable suspicion they're in the country illegally, saying it would undoubtedly lead to racial profiling.
