In a letter sent to the clandestine agency, the senators allege the CIA has long hidden details about the program from the public and the legislative branch, according to the Associated Press.
Sens. Ron Wyden, of Oregon, and Martin Heinrich, of New Mexico, called for a declassification of the program, though significant parts of their letter, sent in April 2021, were redacted.
The lawmakers say they think the program operated "outside the statutory framework that Congress and the public believe govern this collection."
