"Look around the world, turn on your TV," Ryan said in an interview with WTAQ radio in the election battleground state of Wisconsin. "And what we see in front of us is the absolute unraveling of the Obama administration's foreign policy."
As a security matter, how the Obama administration immediately described the attack has little effect on broader counterterrorism strategies or on the hunt for those responsible for the incident, in which the U.S. ambassador and three other Americans were killed. And Republicans have offered no explanation for why the president would want to conceal the nature of the attack.
But the issue has given Republican presidential nominee Mitt Romney an opportunity to question Obama on foreign policy and national security, two areas that have received little attention in an election dominated by the U.S. economy. Obama's signature national security accomplishment is the military's killing of terrorist leader Osama bin Laden.
Ryan was teeing up the issue for Monday's presidential debate on foreign policy.
"I'm excited we're going to have a chance to talk about that on Monday," Ryan said.
Obama, speaking Thursday on Comedy Central's "The Daily Show," insisted that information was shared with the American people as it came in. The attack is under investigation, Obama said, and "the picture eventually gets filled in."
"What happens, during the course of a presidency, is that the government is a big operation and any given time something screws up," Obama said. ''And you make sure that you find out what's broken and you fix it."
The report from the station chief was written late Wednesday, Sept. 12, and reached intelligence agencies in Washington the next day, intelligence officials said. It is not clear how widely the information from the CIA station chief was circulated.
U.S. intelligence officials have said the information was just one of many widely conflicting accounts, which became clearer by the following week.
But former CIA station chief Fred Rustmann Jr. says the White House would have been aware of it.
"When things go down like that, there is no analysis in between," said Rustmann, who has separately accused the Obama administration of sharing too many details about the raid that killed bin Laden. "You report this raw information as you receive it in Sitrep (situation report) format, from the CIA station to concerned worldwide (CIA) stations and bases and to the White House, Pentagon and State Department."
Only afterward would those initial reports be compiled and cross-checked by analysts with other information, he said.
Democrats have spent the past week explaining the administration's handling of the attack. On Monday, Secretary of State Hillary Rodham Clinton said a period of uncertainty typically follows attacks.
"In the wake of an attack like this, in the fog of war, there's always going to be confusion," Clinton said. "And I think it is absolutely fair to say that everyone had the same intelligence. Everyone who spoke tried to give the information that they had."
On Tuesday, Obama and Romney argued over when the president first called it a terrorist attack. In his Rose Garden address the morning after the killings, Obama said, "No acts of terror will ever shake the resolve of this great nation, alter that character or eclipse the light of the values that we stand for."
But Republicans said he was speaking generally and didn't specifically call the Benghazi event a terror attack until weeks later. Until then, key members of the administration were blaming an anti-Muslim movie circulating on the Internet as a precipitating event.
This Wednesday, the chairwoman of the Senate Intelligence Committee, Dianne Feinstein, D-Calif., put the blame on the director of national intelligence James Clapper.
"I think what happened was the director of intelligence, who is a very good individual, put out some speaking points on the initial intelligence assessment," Feinstein said in an interview with news channel CBS 5 in California. "I think that was possibly a mistake."
Congress is asking the administration for documents about the attack, in hopes of building a timeline of what the government knew and when.
"The early sense from the intelligence community differs from what we are hearing now," Rep. Adam Schiff, D-Calif., said. "It ended up being pretty far afield, so we want to figure out why."
Rep. William "Mac" Thornberry, R-Texas, a member of the House Intelligence and Armed Services committees, said: "How could they be so certain immediately after such events, I just don't know. That raises suspicions that there was political motivation."
Obama has weathered similar criticisms before. After both the failed bombing of a U.S.-bound airliner on Christmas Day 2009 and the attempted car bombing in Times Square in 2010, the Obama administration initially said there were no indications of wider terrorist plots. The Christmas Day bomber turned out to be linked to al-Qaida and the Times Square bomber was trained by the Pakistani Taliban.
Nevertheless, polls have consistently showed voters trust Obama over Romney to handle terrorism.
