Obama: 'The Buck Stops With Me' on National Security
President Obama said Thursday afternoon that in regard to terror threats against the United States, "the buck stops with me."
He suggested that nobody would be fired as a result of the attempted airliner attack on Christmas, saying that the security problems were a "systemic failure across organizations and agencies."
The president said he's ordering changes about how information about potential threats is handled and said intelligence agencies must assign "clear lines of responsibility" for immediately pursuing leads on such threats.
