Brennan works for NBC

In the old days, America’s top spies would complete their tenures at the CIA or one of the other Washington puzzle palaces and segue to more ordinary pursuits. Some wrote their memoirs. One ran for president. Another died a few months after surrendering his post. But today’s national-security establishment retiree has a different game plan. After so many years of brawling in the shadows, he yearns for a second, lucrative career in the public eye. He takes a crash course in speaking in soundbites, refreshes his wardrobe and signs a TV news contract.
