Senate Grills FBI on Anthrax, Ivins

Senators cast strong doubts today on the FBI's conclusion that Bruce Ivins acted alone in the 2001 anthrax scare, reports the Washington Post, with many demanding a more public vetting of the investigation into America’s largest bioterror attack. "There are others out there who should be charged with murder," said Sen. Pat Leahy, himself the target of an anthrax-laced letter.

FBI director Robert Mueller assured lawmakers that investigators "have looked at every lead and will continue to do so," even after the case is closed. The agency had announced yesterday that the National Academy of Sciences will review the DNA evidence used to trace the anthrax spores back to a flask in an army lab, but senators want more oversight.
