Allegations that the Obama administration lied to the American people about the Benghazi terrorist attack have been in the air for the last three years, but new information shows that these allegations have a lot more bite to them than Obama and Hillary Clinton would like the public to believe.

Two days after terrorists besieged the U.S. embassy in Libya, Clinton confidant Sidney Blumenthal sent her a memo that repudiated the idea that the attack was the result of a video critical of Islam. According to the memo, there was ample evidence that the attack had been planned by an Al Qaeda affiliate that was merely using the protests as a coverup.

“We should get this around ASAP,” Clinton reportedly told a close adviser after reading the memo. But there was apparently a change of heart, because U.N. Ambassador Susan Rice went on the Sunday shows a few days later, still spreading the story that the Benghazi attack was an outgrowth of the protests.

Later, of course, the State Department and the president were forced to acknowledge that there had been no protests in Benghazi on the day of the attack. Officials and analysts continue to debate how much of a role – if any – the video played in the attack, but it is known to a certainty that it was not the whole catalyst. There is, in fact, much more evidence that the attack was planned as a retaliation for a drone strike that killed an Al Qaeda strategist in Pakistan.

The American people deserve to know why the Obama administration tried to silence the truth about this attack. Were they trying to deflect blame? Avoid allegations of incompetence? Or was it something more sinister? Hillary Clinton, Susan Rice, and perhaps even Barack Obama himself need to answer for these discrepancies, and Congress should accept nothing less than their full cooperation with the investigation. The more we dig beneath the surface on this tragedy, the more it stinks.

It is most unfortunate that the word Benghazi has come to be associated with a right-wing witch hunt in the eyes of the public. Democrats have been successful in denying any culpability, insisting that this is nothing more than political gamesmanship. With the full compliance of the mainstream media, they have brainwashed the voters into believing a lie. And that lie deserves to be exposed.

We’re used to a certain amount of shadiness when it comes to Washington politics, but when American military men and women are dead, we must not stop until we get to the bottom of this coverup. This is about much more than emails, private servers, and multiple devices. This is about secrecy and deception at the highest levels of the U.S. government. And until we know why it happened, no one should think for a moment about voting for Hillary Clinton.
