Because of the job transfer, Shapiro's order to remove Pollard's security clearances slipped through the cracks. However, Shapiro's office followed up with a request to TF-168 that Pollard be investigated by the CIA. The CIA found Pollard to be a risk and recommended that he not be used in any intelligence collection operation. A subsequent polygraph test was inconclusive, although it did prompt Pollard to admit to making false statements to his superiors, prior drug use, and having unauthorized contacts with representatives of foreign governments. The special agent administering the test felt that Pollard, who at times "began shouting and shaking and making gagging sounds as if he were going to vomit", was feigning illness to invalidate the test. He recommended against Pollard's being granted access to highly classified information. Pollard was also required to be evaluated by a psychiatrist.
