Inside 'Operation Absolute Resolve,' the U.S. Effort to Capture Maduro

In August, a clandestine team of C.I.A. officers slipped into Venezuela with a plan to collect information on Nicolás Maduro, the country's president, whom the Trump administration had labeled a narco-terrorist.

The C.I.A. team moved about Caracas, remaining undetected for months while it was in the country. The intelligence gathered about the Venezuelan leader's daily movements — combined with a human source close to Mr. Maduro and a fleet of stealth drones flying secretly above — enabled the agency to map out minute details about his routines.
