Drip, Drip,Drip…like a leaky faucet with each passing day we learn of another Obama attempt to block the people of this country from finding out what happened in Benghazi on September 11, 2012. Through great investigative work by the always reliable Jake Tapper we learn that dozens of people working for the CIA were on the ground during the attack, and that the agency is going all out to make sure whatever it was doing, remains a secret.

CNN has learned the CIA is involved in what one source calls an unprecedented attempt to keep the spy agency’s Benghazi secrets from ever leaking out.

Since January, some CIA operatives involved in the agency’s missions in Libya, have been subjected to frequent, even monthly polygraph examinations, according to a source with deep inside knowledge of the agency’s workings.

The goal of the questioning, according to sources, is to find out if anyone is talking to the media or Congress.

It is being described as pure intimidation, with the threat that any unauthorized CIA employee who leaks information could face the end of his or her career.

In exclusive communications obtained by CNN, one insider writes, “You don’t jeopardize yourself, you jeopardize your family as well.”

Another says, “You have no idea the amount of pressure being brought to bear on anyone with knowledge of this operation.”

“Agency employees typically are polygraphed every three to four years. Never more than that,” said former CIA operative and CNN analyst Robert Baer.

What were the agents doing there?  There is the suspicion supported by Rand Paul that there is some sort of weapons to Syria program run out of Libya but there is no actual evidence. 

“If somebody is being polygraphed every month, or every two months it’s called an issue polygraph, and that means that the polygraph division suspects something, or they’re looking for something, or they’re on a fishing expedition. But it’s absolutely not routine at all to be polygraphed monthly, or bi-monthly,” said Baer.

According to the investigation, there were 35 other people in Benghazi at the time of the attack, seven were wounded, some seriously.

While it is still not known how many of them were CIA, a source tells CNN that 21 Americans were working in the building known as the annex, believed to be run by the agency.

 U.S. Rep. Frank Wolf, whose district includes CIA headquarters in Langley, Virginia, believes there is a cover up going on.

“We should have the people who were on the scene come in, testify under oath, do it publicly, and lay it out. And there really isn’t any national security issue involved with regards to that,” he said.

Wolf has repeatedly gone to the House floor, asking for a select committee to be set-up, a Watergate-style probe involving several intelligence committee investigators assigned to get to the bottom of the failures that took place in Benghazi, and find out just what the State Department and CIA were doing there.

More than 150 fellow Republican members of Congress have signed Wolf’s request for a special committee, and just this week eight Republicans sent a letter to the new head of the FBI, James Comey, asking that he brief Congress within 30 days. Unfortunately Speaker Boehner does not agree with a select committee because…er…well, for no good reason.

Speculation on Capitol Hill has included the possibility the U.S. agencies operating in Benghazi were secretly helping to move surface-to-air missiles out of Libya, through Turkey, and into the hands of Syrian rebels.

But there is no proof this is true, however it may be credible. Certainly if these CIA agents are freed to speak with congress we will get closer to the truth.

It is clear that two U.S. agencies were operating in Benghazi, one was the State Department, and the other was the CIA.

The State Department told CNN in an e-mail that it was only helping the new Libyan government destroy weapons deemed “damaged, aged or too unsafe retain,” and that it was not involved in any transfer of weapons to other countries.

But the State Department also clearly told CNN, they “can’t speak for any other agencies.”

Clearly there is something we are not being told about the Benghazi terror attack, and clearly house leadership is not allowing the legislative body to investigate this attack as best as it can. This is not a political Issue, the American people deserve the  full story of the Benghazi Attack/cover-up and why things were done the way they were done.  A select committee can generate the pressure need to turn over each stone, to subpoena the necessary witness and get the answers “we the people”have been demanding.
