Latinos and immigrant rights activists are holding a national day of action today to oppose the Obama administration’s recent decision to expand the controversial immigration program known as Securities Communities. Secure Communities requires local police to forward fingerprints of every person they arrest to the U.S. Department of Homeland Security. In recent months, the governors of Illinois, Massachusetts and New York have pulled out of the program. But earlier this month federal officials announced the program is not voluntary and that local governments cannot opt out. Rallies are planned in Atlanta, Georgia; Boston, Massachusetts; Charlotte, North Carolina; Houston, Texas; and Miami, Florida. The activists plan to deliver thousands of petitions to President Obama’s national campaign headquarters in Chicago.
