I am pleased that the State Department is set to designate Ansar al-Sharia as Foreign Terrorist Organization. The killers behind the Benghazi attack are still at large. Sixteen months later, no one has been brought to justice. Designating Ansar al-Sharia as an FTO is an encouraging first step, but as always, action is required to ensure that Ansar al Sharia is not treated by the United States as a terrorist organization in name only. We must use all resources available to understand its networks and operatives, how they move money around and resource their operations, and finally, freeze and seize their finances. In order to be effective, we must use all available tools that the U.S. government has at its disposal to go after these terrorists.
