Reading this snippet from Wikipedia makes it look like Clinton was not exactly doing a bang up job.
According to a local security official, he and a battalion commander had met with U.S. diplomats three days before the attack and warned the Americans about deteriorating security in the area. The official told CNN that he advised the diplomats, "The situation is frightening, it scares us."[61]
Ambassador Stevens' diary, which was later found at the unsecured site of the attack, recorded his concern about the growing al-Qaeda presence in the area and his worry about being on an al-Qaeda hit list.[62]
U.S. security officer, Eric Nordstrom, twice requested additional security for the mission in Benghazi from his superiors at the State Department. His requests were denied. According to Nordstrom, State Department official, Charlene Lamb, wanted to keep the security presence in Benghazi "artificially low".[63]
On December 30, 2012, the United States Senate Committee on Homeland Security and Governmental Affairs released a report, “Flashing Red: A Special Report on the Terrorist Attack at Benghazi,” wherein it was determined:
In the months [between February 2011 and September 11, 2012] leading up to the attack on the Temporary Mission Facility in Benghazi, there was a large amount of evidence gathered by the U.S. Intelligence Community (IC) and from open sources that Benghazi was increasingly dangerous and unstable, and that a significant attack against American personnel there was becoming much more likely. While this intelligence was effectively shared within the Intelligence Community (IC) and with key officials at the Department of State, it did not lead to a commensurate increase in security at Benghazi nor to a decision to close the American mission there, either of which would have been more than justified by the intelligence presented. ... The RSO [Regional Security Officer] in Libya compiled a list of 234 security incidents in Libya between June 2011 and July 2012, 50 of which took place in Benghazi.[64]
The desire of Hillary Clinton's State Department to maintain a low profile in Benghazi has been cited as the reason why the State Department circumvented their own Overseas Security Policy Board (OSPB) standards for diplomatic security.[65]:74-75 In the aftermath, Secretary of State Clinton sought to take responsibility for the security lapses at Benghazi and expressed personal regret.[66] However, in her January 2013 testimony before Congress, Secretary Clinton claimed security decisions at the Benghazi compound had been made by others, stating, "The specific security requests pertaining to Benghazi ... were handled by the security professionals in the [State] Department. I didn't see those requests, I didn't approve them, I didn't deny them."[67]
