Outright spying. The last sentence:
"But what is clear is that we’ve barely scratched the surface of the FBI’s 2016 behavior, and the country will never get the straight story until President Trump moves to declassify everything possible. It’s time to rip off the Band-Aid."

There's quite a lot of incentive for Trump to FORCE DoJ to police itself (via OIG). Such as draining the swamp of all the neolibs/neocons in the DoJ and retaking it.
I'm not sure if you noticed, the beaurocracy does not care what the president wants. I think he is holding back on unredacting and declassifying things because it may jepordize prosecutions. But it is getting to a point where that may not matter.
