(Newser) – The FBI's case against alleged anthrax killer Bruce Ivins is full of gaps and contradictions, Newsweek reports. Ivins is said to have sent anthrax to NBC's Tom Brokaw—but was retaliating against a reporter at ABC. He also passed a polygraph in the probe and had no anthrax in his cars, clothing, or home. "I'd say the vast majority" of his ex-colleagues "think he had nothing to do with it," a former supervisor said.

US Attorney for the District of Columbia Jeffrey Taylor called Justice officials "confident" that Ivins was "the only person responsible for these attacks"—but Congress will likely review the case. "There are clearly a lot of unanswered questions," said Iowa GOP Sen. Charles Grassley, who has called for a full investigation into the Ivins evidence.
