Meanwhile, the Senate committee's report suggests U.S. officials still have their own unanswered questions themselves about the Benghazi attacks.
"It remains unclear if any group or person exercised overall command and control of the attacks or whether extremist group leaders directed their members to participate," according to the report, whose authors had access to some of the most sensitive intelligence in the U.S. government's possession. "Intelligence suggests that the attack was not a highly coordinated plot, but was opportunistic … Some intelligence suggests the attacks were likely put together in short order, following that day's violent protests in Cairo against an inflammatory video."
In light of all that, Comey today was once again pushed to answer for what critics describe as a key U.S. shortcoming: the inability to arrest, much less convict, any suspects.
"We will never give up on this matter until we have the people responsible in our custody … no matter how long it takes," Comey said. "The one thing we don't do at the FBI is ever forget."
Last week, Comey was similarly asked about justice in the Benghazi attacks during a Senate Intelligence Committee hearing. And Attorney General Eric Holder faced similar questioning last week during a Senate Judiciary Committee hearing.
"We are determined to hold accountable the people who are responsible for that attack," Holder said, "and we will take and use all measures of the American government in order to effectuate that desire."
Asked today whether any Benghazi suspects might be brought to the detention facility at Guantanamo Bay if captured by U.S. personnel, Comey said such a decision is "not a judgment for the FBI to make, but I'm sure that all options will be looked at by the government."
