In August of 2017, Sen. Chuck Grassley sent a letter to Secretary of Defense James Mattis and the director of the Defense Intelligence Agency (DIA) Lt. Gen. Vincent R. Stewart, in which he revealed that his Senate Judiciary Committee had been shown some highly classified documents by current DIA personnel back on May 25.
In his letter, Grassley specifically requested that Mattis and Stewart declassify at least one particular piece of information in these documents out of fairness to Flynn. He wrote:
“Based on representations made by the DIA personnel, it appears the public release of this information would not pose any ongoing risk to national security. Moreover, the declassification would be in the public interest, and is in the interest of fairness to Lt. General Flynn.”
