It’s unclear which documents Trump has ordered declassified less than 24 hours before he leaves office. He cited the decision as based on the results of a Dec. 30 review he asked the Justice Department to perform. The department presented him with a “binder of materials” that remain classified, he said in a memorandum issued on Tuesday. Trump said he then asked for the documents to be declassified to “the maximum extent possible.”

The FBI responded that it believed that all of the materials should remain classified, but that some were particularly crucial and should at least be redacted.

“I have determined to accept the redactions proposed for continued classification by the FBI in that January 17 submission,” Trump said in his memo. “I hereby declassify the remaining materials in the binder. This is my final determination under the declassification review and I have directed the Attorney General to implement the redactions proposed in the FBI’s January 17 submission and return to the White House an appropriately redacted copy.”

It’s unclear when the newly declassified documents will become public. But Trump’s decision represents a sharp walkback from two previous assertions that he would declassify every document related to the probe, a longtime demand of his political allies, who have amplified his denigration of the investigation.
