I remember Sydney Powell in court with judge Sullivan and when he asked her about her conversation with President Trump she would only say she had a conversation but said something to that nature that she could not discuss the subject matter and I think she said because it's classified or hinted such.
I do believe that a phone call with the President is considered classified or confidential, and only the President can declass it. Am I right?

Trump Claims John Bolton Has 'Broken the Law' Because 'Every Conversation' with Him Is Classified
Responding to reports that he intends to file a lawsuit against Bolton, Trump said:
"Somebody said he went out and wrote a book…I can't imagine that he can because that's highly classified information. Even conversations with me, they're highly classified. I told that to the Attorney General before. I will consider every conversation with me as President highly classified, so that would mean that if he wrote a book…he's broken the law. And I would think that he would have criminal problems, I hope so."
