Chertoff: European terrorists trying to enter US"The terrorists are deliberately focusing on people who have legitimate Western European passports, who don't appear to have records as terrorists," Chertoff told lawmakers. "I have a good degree of confidence we can catch people coming in. But I have to tell you ... there's no guarantee. And they are working very hard to slip by us."
Chertoff and other intelligence officials have delivered similar warnings before, and he offered no new information about specific threats or an imminent attack.
