FBI agents investigating government watchdog Scott Bloch have subpoenaed any records that would reveal whether concerns about the 2004 elections prompted him to clear Secretary of State Condoleezza Rice of ethics violations. Bloch found no merit to allegations that Rice, then President Bush's national security adviser, timed some of her trips to boost Bush's 2004 reelection campaign. It's unclear whether the FBI is looking into Bloch's decision to clear Rice or whether agents are seeking evidence in separate obstruction and false-statements investigation.
