The head of the House Homeland Security Committee said Monday the United States must temper victory with vigilance in the wake of Osama bin Laden's assassination.
Rep. Peter King told NBC's "Today" show the al-Qaida terrorist organization could "try to avenge this death" and says "we'll have to be on full alert."
Bin Laden was killed by U.S. military forces in a raid early Monday on his custom-built hideout in Pakistan.
The New York Republican predicted "a fight for power" within al-Qaida. He said the shooting of bin Laden gives "a sense of closure" to the relatives of people killed in the Sept. 11, 2001 terror attacks on the United States. King also said there will be "round-the-clock" government surveillance to determine if al-Qaida is planning or organizing a retaliatory attack. He said federal agencies will be trying to find out if an attack is possible or imminent, "and how we can prevent it, how we can stop it."
