The President can make that decision, it is part of his powers as President. He isn't prohibited from doing that. Perhaps you don't think something in particular should have been released. If so make that case, but just complaining about this in general is illogical.

> fighting with his intelligence agencies

You mean the intelligence agencies that have worked very hard to delegitimize his presidency, mislead the FISA court and so on? Those agencies have a lot to answer for and shouldn't be treated as infallible.

> suppressing the press

Really? The press seems quite free to say whatever they want under Trump. It just seems silly to say that Trump is limiting the press.
