Hundreds of thousands of immigrants and immigrant rights activists are planning to rally across the country today on the anniversary of last year’s historic May Day protests. Marches are planned in at least 75 cities across the country. Some of the largest protests are expected to take place in Los Angeles and Chicago. Several groups are calling for a boycott of work, school and all consumer activity today. In California, youth organizers said walkouts were planned in at least 20 Los Angeles middle schools and high schools. In Chicago, some 700 businesses are expected to close down today as part of the national boycott. In Fresno, organizers are holding a rally focusing on children whose parents have been deported. Groups are calling on Congress to reject all anti-immigrant legislation, to stop the government raids on immigrant communities, to stop President Bush’s proposed guest worker program and to demilitarize the U.S.-Mexican border.
