New York Times correspondent David Johnson reports. Excerpt:
WASHINGTON, April 3 – About seven F.B.I. employees with access to highly classified information have been unable to pass polygraph examinations administered as part of the bureau’s stepped-up security program after the arrest last year of a senior agent as a Russian spy, F.B.I. officials said today.
At a meeting with reporters at Federal Bureau of Investigation headquarters, Robert S. Mueller III, the director, said that about 700 bureau employees had been given polygraph exams in the aftermath of the arrest of Robert P. Hanssen, who has pleaded guilty to spying for Moscow.
Mr. Mueller said, “We are heartened that less than 1 percent of the 700 raised issues that require further investigation.”
