Executive privilege is the right to confidentiality in papers and conversations relevant to the conduct of the affairs of state.
Executive privilege allows SPECIFIC documents and conversations to be designated as necessarily confidential for the conduct of official business.
Executive privilege can NOT be a blanket, general order against any and all cooperation.
Executive privilege can NOT be used solely to prevent legitimate legislative oversight, especially by the person whose conduct is being looked into. That is not executive privilege; that is OBSTRUCTION.
