In January of 2013, U.S. Senator Ron Johnson became a Tea Party hero when he repeatedly interrupted then-Secretary of State Hillary Clinton during her testimony before the Senate Foreign Relations Committee. Johnson's central theme then, as now, was that in order to help President Obama's re-election bid, Clinton was involved in a massive cover-up of the actual events before and after the September 11, 2012, attack on a U.S. facility in Benghazi, Libya.
In a nutshell, Johnson's conspiracy theory goes like this: The Obama administration was warned at the highest levels that a terrorist attack on the Benghazi embassy was imminent, but because that didn't play well with the Obama campaign narrative that he had successfully choked out the threat of extremist Islamic terrorism, the administration turned a blind eye to cries from the embassy for added security. Then, when terrorists attacked the embassy, instead of telling the American people the truth in the days immediately following the attack, the administration tried to conceal the terrorist attack by saying that it was the result of a protest over a derogatory Islamic video that boiled over into a riot.
