Chertoff addresses ABC News terrorist report

ABC News’ Mary Bruce and Suhas Subramanyam report: In the wake of this week’s terrorist attacks in Britain, Homeland Security Secretary Michael Chertoff addressed an ABC report that the U.S. was aware of a threat to the Glasgow airport. "Whatever information the U.S. government and intelligence community had was shared very readily with our British counterparts," he assured ABC News’ George Stephanopoulos in a "This Week" interview.  Chertoff would not, however, comment on any specific intelligence the administration may have had about the plots before they occurred.

Despite the two thwarted car bombs in London and the attack on Glasgow’s Airport, Chertoff said "we do not have any specific credible evidence that there’s an attack focused on the United States at this point." He said travelers will see an increased security presence at airports but that his department will not change the U.S. threat level for aviation.  The administration raised the threat level to Orange, or "high" risk of an attack, in August following a foiled bomb plot involving a London plane bound for the U.S.
