Trump declassified everything before he left office. Plus: Fairly sure as President, he had already invoked. Or he will invoke Executive Privilege. Executive privilege is the power of the President and other officials in the executive branch to withhold certain forms of confidential communication from the courts and the legislative branch.

The Constitution is silent on the executive power to withhold information from the courts or Congress; the privilege is rooted in the separation of powers doctrine that divides the power of the United States government into legislative, executive and judicial branches.
