Senator Ron Wyden has expressed concerns about a secret program called the Hemisphere Project, which allows law enforcement agencies to conduct searches of trillions of phone records without warrants. Under this program, telco AT&T is paid by the White House Office of National Drug Control Policy to provide access to domestic phone records dating back to 1987, as well as the four billion call records added every day. Senator Wyden has called on the Justice Department to reveal information about this surveillance program, describing it as a “long-running dragnet surveillance program” that raises serious legal concerns.
