The Federal Bureau of Investigation is denying allegations of targeting innocent Muslims through a counter-terrorism program.
Muslim groups and the American Civil Liberties Union is accusing the FBI of sending undercover agents into mosques without proper cause, and that, racial and ethnic profiling is being used.
FBI Director Robert Mueller denied those claims on Wednesday and told Congress that the domestic surveillance guidelines are being enforced fairly.
The guidelines "do not target based on race," he said.
The FBI has said they would only investigate a mosque if there was suspicion of criminal activity. But Farhana Khera, with the group Muslim Advocates, argues the FBI has lowered its standards.
The guidelines, which were set in place by the Bush administration, also allow agents to monitor financial transactions and employment history to track what the FBI calls genuine national security threats.
The ACLU has asked the FBI in 29 states to turn over their records on the collection of data on race and ethnicity.
