Here is an update on the story. The U.S. was forced to admit its use of the base for attacks on Pakistani militants from within Pakistan. The reporting in the story calls Feinstein's statement in the meeting a "blooper".
From FoxNews:
Feinstein's Blurt Leads to U.S. Confirmation That It Uses Pakistani Air BaseThe Senate intelligence committee chairwoman claims to have learned from open sources that the U.S. was operating unmanned drones on a Pakistani air base, something the U.S. had denied -- until her blooper.
Sen. Dianne Feinstein's blurt during a Senate Intelligence Committee hearing last week forced the U.S. intelligence and military community to acknowledge on Thursday that the U.S. is targeting Al Qaeda and Taliban operatives using unmanned drones based in Pakistan.
The senator's slip sent reporters into overdrive and led to the discovery of a 2006 picture provided by Google Earth that appears to show Predator drones at Shamsi air base 200 miles southwest of Quetta.
A senior U.S. official confirmed to FOX News that Pakistani leaders -- despite their public protests and denials -- have been giving the U.S. some targets in the tribal areas of their own enemies, and have given the U.S. blanket permission to go after any "Arabs" in those areas because they are assumed to be Al Qaeda operatives.
