In a wide-ranging interview moderated by Fox News’ Catherine Herridge, Thomas, who leads the Special Operations Command, said his team was “particularly close” to Baghdadi after the 2015 raid that killed ISIS oil minister Abu Sayyaf. That raid also netted his wife, who provided a wealth of actionable information.

“That was a very good lead. Unfortunately, it was leaked in a prominent national newspaper about a week later and that lead went dead,” Thomas said. “The challenge we have [is] in terms of where and how our tactics and procedures are discussed openly. There’s a great need to inform the American public about what we’re up to. There’s also great need to recognize things that will absolutely undercut our ability to do our job.”

Thomas appeared to be referring to a New York Times report in June 2015 that detailed how American intelligence agencies had “extracted valuable information.”
