President Barack Obama broke his silence Monday on the failed bombing of Northwest Airlines flight 253 from Amsterdam to Detroit. Obama said the U.S. was working to review airport screening procedures. The president also sought to reassure airline passengers.

Obama has been criticized for remaining silent for three days on what could have been a catastrophe. He denied that his administration has been soft on terror.

As millions endured stringent new security measures at airports and on flights around the globe, the pressure mounted on Obama, vacationing in Hawaii with his family, to ease frayed nerves.
