The White House is revoking the security clearance of ex-CIA director John Brennan. In confirmation the move, Press Secretary Sarah Sanders accused Brennan of lying to the American public on a variety of sensitive issues. She added Brennan has made a series of "unfounded and outrageous statements" about the Trump administration.
But if the intention was to silence those listed from speaking out against the administration, it didn’t work. Brennan himself took to Twitter following the decision. “This action is part of a broader effort by Mr. Trump to suppress freedom of speech & punish critics,” Brennan wrote. “It should gravely worry all Americans, including intelligence professionals, about the cost of speaking out. My principles are worth far more than clearances. I will not relent.”
In this new day age of 24/7 news networks and social media, I think you have to look at those holding security clearances more closely. Expressing opinions and answering questions as a pundit on TV or online exposes these people to the possibility of spilling the beans concerning sensitive info they've been privy to. In other words, loose lips sink ships.
