Senate intelligence panel member Ron Wyden (D-Org.) raised the issue of transparency on Thursday, pressing Brennan on whether CIA would publicly accept responsibility for mistakenly labeling an individual as a terror suspect and taking them out via armed drones.

Surprisingly, Brennan told Wyden and the Senate panel that under his leadership, CIA would be willing to publicly admit when an individual is mistakenly targeted and taken out by U.S. drones.

“As far as I am concerned … the U.S. should [publicly] acknowledge it,” he told the Senate panel.

Public admission of a mistaken drone strike, or the strike itself, would represent a break from the classified status of the entire U.S. armed drone strike program.
