Demonstrations in support of immigrants' rights are scheduled Saturday in at least 21 states, the District of Columbia and two Canadian provinces. In all, protests are planned for 47 cities.
The demonstrations come amid a swirl of controversy surrounding a new immigration law in Arizona that allows police to demand proof of legal residency. Arizona lawmakers say the law is needed because the federal government has failed to enforce border security with Mexico, allowing more than 450,000 illegal immigrants to move into in the state.
Critics say the law is unconstitutional and will lead to racial profiling, which is illegal. But Republican Arizona Gov. Jan Brewer and others who support SB1070 say it does not involve profiling or other illegal acts.
