FBI Director Robert Mueller has revealed there was no imminent threat in the case of an Afghan immigrant accused of plotting a bombing attack on US soil. Twenty-four-year-old Najibullah Zazi is being held on charges of acquiring and preparing explosive materials. On Wednesday, Senator Joe Lieberman questioned Mueller about the alleged plot at a Senate Homeland Security Committee hearing.

Senator Joe Lieberman: “There have been some discussion in the media as to whether there remains an imminent threat related to the Zazi plot.”

FBI Director Robert Mueller: “We do not believe there is an imminent threat.”
