Senators seek delay in terror probe rules WASHINGTON (AP) — New rules on FBI investigations of national security cases should be delayed, top Senate Judiciary Committee members said Monday, raising concerns that ethnic or racial groups could be targeted despite no evidence of wrongdoing. In a letter to Attorney General Michael Mukasey, the senators called for congressional hearings on the rules before they are finalized. They suggested delaying the rules — known as the attorney general guidelines — until FBI Director Robert Mueller appears before the panel Sept. 17. |
