I knew it would be projection before looking it up, but just to confirm:

Earlier Tuesday, Director of National Intelligence John Ratcliffe declassified documents revealing that then-CIA Director John Brennan briefed President Obama in 2016 on Hillary Clinton’s “plan” to stir up a scandal tying then-candidate Donald Trump to Russia and distracting from the controversy over her private email server.

So Hillary invented the Russia investigation to distract from the email "scandal" that Trump had whipped up. And declassifying this now serves what investigatory purpose?

“I hope that the president’s declassification and removal of the redactions shed light on that because this does appear to be a criminal conspiracy,” he said.

How would declassifying accomplish that? Any actual investigation can be staffed by people with clearance. The only reason to declassify is so Joe Schmoe can see it. Or more accurately, so Fox News can selectively quote from it.
