WASHINGTON - In the wake of the Christmas Day bombing attempt on a Northwest Airlines plane over Detroit, President Barack Obama is preparing to tell the nation how he plans to prevent future terrorist attacks.
The White House says Obama today will be outlining changes to the lists of suspected terrorists that the government maintains.
His comments will follow a meeting on air security with 20 officials.
They've been reviewing the screening of airline passengers, as well as the watch-list system.
Secretary of State Hillary Rodham Clinton, Defense Secretary Robert Gates, Homeland Security Secretary Janet Napolitano, CIA Director Leon Panetta and FBI Director Robert Mueller are among those who will attend.
