(CNN) - The Department of Homeland Security has significantly increased the number of air marshals on flights since a failed Christmas terrorist attack on a U.S. jetliner, a department official told CNN Sunday.
The official, who asked not to be identified, said the ranks of the marshals have been increased by cutting vacations and leave and by pulling in air marshals from instructional and administrative posts.
Homeland Security Secretary Janet Napolitano said there is no indication so far that the attack was part of a broad international effort.
So, how did the suspect get through security? And does the government need to do more to keep you safe in the air? Sec. Napolitano joined us on Monday's American Morning.
