New information released today on the deadly attack on the U.S. Consulate in Libya suggest Washington knew it was not caused by a derogatory film on Islam on YouTube.

U.S. officials say the CIA station chief in Libya reported to Washington within 24 hours there was evidence suggesting the attack was carried out by terrorists, not by a mob upset over the trailer from an American-made video.

According to intelligence officials, the station chief's report was written late Wednesday, Sept. 12, and reached intelligence agencies in Washington the following day.

It is unclear who, outside of the CIA, received the information.

The Obama administration did not officially call the Benghazi attack a terror attack until weeks after it took place. Rather the president and top administration officials repeatedly claimed the video sparked the attack

The president defended his administration's handling of the attack on "The Daily Show" with Jon Stewart.

Stewart asked the president if problems had been a factor in the White House response to the attack, saying, "Even you would admit it was not the optimal response."

The president replied, "Here's what I'll say. When four Americans get killed, it's not optimal. We're going to fix it -- all of it."   

"We weren't confused about the fact that four Americans had been killed," Obama continued. "I wasn't confused about the fact that we needed to ramp up diplomatic security around the world right after it happened."

The president said the United States will hunt down whoever carried out the attack.
