WASHINGTON -- The Department of Homeland Security should conduct an investigation into whether its officials intentionally misled the public and local officials in order to coerce them into participating in an immigration enforcement program, Rep. Zoe Lofgren (D-Calif.) said in a Thursday letter to the agency.Lofgren, the top Democrat on the House immigration subcommittee, asked top DHS oversight officials to look into conflicting statements made by the agency last year about the Secure Communities program.Secure Communities shares fingerprint data taken by local police, which is already sent to the FBI, with immigration officials to check whether individuals are in the country illegally.
