It merely points out the fact that Trump cares not about tradition.
If his being allowed access is merely tradition, then I say dump his *** like yesterdays garbage.
The point of allowing ex-presidents access to current intelligence is so they can be up to speed should the current president feel the need for the sort of advice that ex-presidents are usually more qualified to give them than most anyone else. I can imagine that might include tips on what works when dealing with foreign leaders and other high ranking officials. It's said to be largely about foreign relations.
I haven't heard there's a law says an ex-president must get it. There doesn't seem to be any necessary 'legal channels' to go through.
I don't think it would take anyone much Google time to get a good, working idea of the damage that could be done if even a fragment of a daily brief got into the wrong hands. Those things are said to pack top secrets together like sardines in a can.
It would be so irresponsible to let Trump 'get away with releasing one' before closing him down on the bleeding-heart notion anyone needs to be kind to the man. The one 'he got away with releasing' might be one that gets someone killed. Early in his presidency, Trump told a Russian diplomat enough to alarm many American allies about the safety and security of their spies. I don't know if this part is true, but people have said countries quickly cut off the US from some information they'd have in normal times passed along.
If in the future a Republican president takes office and decides to play partisan with who gets those briefings, well then they are cutting off their access to advice from former presidents who are up to date and ready to give it. If they are that big of fools, they aren't likely to ask for advice anyway.
Cut Trump off. That's a no brainier. What could it mean that Biden is dragging his heels on it?
