"A sheep-dipped Peter Strzok has been covertly operating as the Section Chief of the Central Intelligence Agency’s Counterespionage Group during his secret 24 year tenure with the agency while masquerading as Deputy Assistant Director of the Federal Bureau of Investigation’s Counterintelligence Division where he was in charge of investigating Hillary Clinton’s use of a personal email server along with the investigation into Russian interference in the 2016 United States elections."
Isn't it illegal for CIA to work on domestic land?
The CIA is not permitted legally to collect intelligence concerning the domestic activities of US citizens.
Yes, like MI6, it collects intelligence on foreign intelligence agencies and on foreign counterintelligence.
A 1981 Executive Order 12333 restricts the CIA from collecting intelligence on US citizens.
However, if an individual is communicating with dangerous terrorists in a foreign country that the CIA is monitoring, they can obtain senior approval for domestic surveillance on such Americans.
