The U.S. government suspects that individuals with connections to al-Qaida and other hostile groups have repeatedly sought to obtain jobs in the intelligence community, and it reinvestigates thousands of employees each year to reduce the threat that one of its own may be trying to compromise closely held secrets, according to a classified budget document.
The CIA found that among a subset of job seekers whose backgrounds raised questions, roughly one out of every five had "significant terrorist and/or hostile intelligence connections," according to the document, which was provided to The Washington Post by former National Security Agency contractor Edward Snowden.
The groups cited most often were Hamas, Hezbollah, and al-Qaida and its affiliates, but the nature of the connections was not described in the document.
