Mr Mueller described the drone use in testimony on Wednesday to the US Senate judiciary committee. He was questioned on the matter by Iowa Republican Chuck Grassley.

He said drones were used in “particular incidents where you need the capability”, adding he was unsure how long images captured by the drones were kept.
