A 13 November 2003 edition of CBS News' "60 Minutes" charged that "eco-terrorists," a term used by the United States government to refer to the Animal Liberation Front and Earth Liberation Front, are considered by the FBI to be "the country's biggest domestic terrorist threat." John Lewis, a Deputy Assistant Director for Counterterrorism at the FBI, stated in a 60 Minutes interview that these groups "have caused over $100 million worth of damage nationwide", and that "there are more than 150 investigations of eco-terrorist crimes underway".
