In 2016, the website Politico ran a story about Democrats'tumultuous relationship with the CIA. After the Senate Intelligence Committee had launched an investigation into the CIA's alleged use of torture, including waterboarding, of suspected terrorist captives, leading Democrats charged that the agency was dragging its feet "and perhaps even intentionally undermining the congressional probe," Politico reported. Sens. Martin Heinrich, a New Mexico Democrat, and Mark Udall, a Colorado Democrat, called for CIA director John Brennan to resign. Now, many Democrats and most of the left are applauding Mr. Brennan for calling President Trump a traitor and demanding he be impeached.
