Senators from both parties are accusing the U.S. Federal Bureau of Investigation (FBI) of excessive secrecy and demanding details of how federal agents use antiterrorist laws to spy on people's Internet activity. The Domestic Surveillance Oversight Act is called "the first comprehensive, public FBI oversight effort in decades" by cosponsor Patrick Leahy, D-Vermont. He is teaming with Republican Senators Charles Grassley of Iowa and Arlen Specter of Pennsylvania to force greater accountability by investigative agencies. All three are members of the Senate Judiciary Committee.
