Former FBI Director James Comey said he has “no idea what the heck” Attorney General William Barr meant when he said there was “spying” on the Trump campaign in 2016.

Comey made the comment at the Hewlett Foundation’s Verify Conference Thursday, according to the Daily Beast.

He reportedly added, “The only thing I can say generally is that I think his career has earned him (Barr) a presumption that he will be one of the rare Trump cabinet members who will stand up for truth and facts…language like this makes it harder, but I still think he’s entitled to that presumption.”
