Although the notorious attack on the U.S. embassy in Benghazi occurred more than a year ago, we still have more questions than answers when it comes to the events that unfolded.

Four people were killed that night, including J. Christopher Steven, the U.S. ambassador to Libya. He was the first ambassador killed by our enemies in more than 30 years. The attack was first blamed on a protest gone wrong, but later analysis showed that the events were much more premeditated.

However, after numerous Congressional panels and an internal investigation, no one has truly been held accountable or faced any kind of disciplinary action.

Now, months after the attack, a recent “60 Minutes” broadcast has brought the events of that night back to light, including for U.S. Sen. Lindsey Graham, R-S.C.

While certain details of the attack remain classified, Graham has indicated that after watching the program, he will try to force the administration’s hand by blocking paths for nominees.

The White House has a deep slate of upcoming nominees, but the South Carolina Republican has plans to hold up nominations until the survivors of the attack are made available to testify to Congress.

The events in Benghazi have been overshadowed by partisanship and misinformation, but that doesn’t negate the fact that the families of those killed deserve answers.

There’s also increasing frustration that security officials saw the attack coming, but did little to prevent it.

The White House’s initial public statement was that there was no indication it was a pre-planned attack. The consensus now is the Americans killed that night were attacked by al-Qaeda in a well-orchestrated strike.

The terrorist organization had already indicated several threats that it had carried out – including trying to assassinate a British ambassador and attacking a Red Cross outpost.

It’s been suggested that Washington ignored the warnings, an allegation we certainly need to more adequately investigate.

The survivors of that night are likely haunted by the attack. Thanks to efforts from Graham and other national leaders, hopefully their story will soon be heard and we can gain some level of clarity.
