I’m not sure what our CIA is doing these days, but an operation to investigate the conception, strategy, logistics and financial support of this prolonged incident, and to disrupt it is exactly what they are paid to do .....
The CIA cannot investigate US Citizens......Its the job of the FBI to do this.
The Central Intelligence Agency's primary mission is to collect, evaluate, and disseminate foreign intelligence to assist the president and senior US government policymakers in making decisions relating to the national security. The CIA does not make policy; it is an independent source of foreign intelligence information for those who do. The CIA may also engage in covert action at the president's direction in accordance with applicable law.
