While that HAS been the practice in DC since the Deep State took control, that practice, is in fact, UnConstitutional.

ONLY the President has the Constitutional Authority to decide what to hide and from whom and what to release and to whom.

No agency, and no one else has the authority to over ride the President or to insist that he do things their way.

However, the President may choose to get input before making a decision. But he does not have to.
