President Donald Trump has given the Central Intelligence Agency secret new authority to conduct drone strikes against suspected terrorists, U.S. officials said, changing the Obama administration’s policy of limiting the spy agency’s paramilitary role and reopening a turf war between the agency and the Pentagon.

The new authority, which hadn’t been previously disclosed, represents a significant departure from a cooperative approach that had become standard practice by the end of former President Barack Obama’s tenure: The CIA used drones and other intelligence resources to locate suspected terrorists and then the military conducted the actual strike. The U.S. drone strike that killed Taliban leader Mullah Mansour in May 2016 in Pakistan was the best example of that hybrid approach, U.S. officials said.

The Obama administration put the military in charge of pulling the trigger to promote transparency and accountability. The CIA, which operates under covert authorities, wasn’t required to disclose the number of suspected terrorists or civilian bystanders it killed in drone strikes. The Pentagon, however, must publicly report most airstrikes.
