On Thursday, CNN’s Jake Tapper reported that the Central Intelligence Agency is now pressuring agents who were on the ground in Benghazi, Libya on the night of September 11, 2012 to keep silent and not talk to Congress or the media. In fact, according to the report, these CIA agents have also been put through numerous polygraph testing in order to ensure they aren’t talking about the Benghazi attacks! They were told that if they talk their career could end and that they would jeopardize themselves and their family.

The Hill reports:

The CIA allegedly had “dozens” of agency operatives on the ground at the U.S. diplomatic annex in Benghazi, Libya, during last year’s deadly terrorist attack that ended with the deaths of Ambassador Christopher Stevens and three other Americans.

Langley is taking extreme measures to mask the agency’s operations in Benghazi and in northern Libya at the time of the strike, according to CNN.

Agency employees involved with CIA operations in the country are being subjected to monthly polygraph tests, among other counterintelligence measures, an unnamed source told CNN.

“Sources now tell CNN dozens of CIA agents were on the ground that night,” Tapper reported, “and the CIA is going to great lengths to make sure whatever they were doing and what happened that night remains a secret.”

“Since January, some CIA operatives involved in the agency’s missions in Libya have been subjected to frequent, even monthly, polygraph examinations,” CNN reporter Drew Griffin said. “The goal of the questioning, according to sources, is to find out if anyone is talking to the media or Congress.”
