WASHINGTON (CNN) - Fears that terrorists might strike in an effort to influence the U.S. presidential elections never came to pass. But the nation's homeland security chief said Wednesday the country needs to remain vigilant during the presidential transition.
"Any time there's a transition there's a danger or a risk that vulnerability (to terror attacks) will increase because people become distracted. People are leaving; people are coming in - and that's a disruptive process for any organization," Homeland Secretary Michael Chertoff said.
"For that reason, we need to take special pains to make sure that we are very focused on the security of this country from now - in fact, from a month ago or two months ago - through the first half, let's say, of 2009," he said.
Chertoff and others have pointed to terror attacks in Glasgow and Madrid, both of which occurred during transfers of power, as evidence that terrorists time attacks to influence elections
"This is not a statement that there's some imminent threat out there," Chertoff said. "It is a recognition of the human reality that in a changing environment, you have to be extra careful to make sure that you don't lose focus on something like homeland security."
He congratulated President-elect Barack Obama for a "masterly, well-run campaign," and Sen. John McCain, saying McCain's "entire career of public service remains an inspiration to everyone in this country."
He said the Department of Homeland Security has prepared briefing books for Obama's transition team, and has trained top civil service employees so they can help manage the department until Obama appointees are situated.
Chertoff said the department expects to start briefing Obama transition officials within a couple of days, and he expects to meet with his successor about "some of the experiences I've had and the issues that I've seen."
In addition, Chertoff said, "It's my hope ... that the new folks coming into leadership positions will sit with us either late this year or early next year to go through some kind of a tabletop instructional course on incident management, so that if something would happen in the month or two after the new
president gets on board that they'd be as prepared as they reasonably can be based on training.
"So I think we've got a good plan in place."
Chertoff said he plans on staying in office until the January 20 transfer of power, and he does not know what he will do thereafter.
