A newly declassified letter written by two senators reveals the CIA has been secretly and illegally carrying out a mass surveillance program on U.S. citizens and residents for years. Senators Ron Wyden and Martin Heinrich called in their letter from April 2021 for more details about the CIA program to be released, and said it was “entirely outside the statutory framework that Congress and the public believe govern this collection, and without any of the judicial, congressional or even executive branch oversight that comes from Foreign Intelligence Surveillance Act collection.”
