Is there any type of "Executive Privilege" for ex-Presidents?

Asking because Trump is citing this now while trying to keep documents from being released to the January 6 Commission and prevent his former aides from being subpoenaed to testify.

Sounds like nonsense to me. The Justice Department has also hinted of this continues they'll being charges against aides who refuse subpoenas.

This is the first I've heard of an ex-President invoking it. I suspect that it might be an untested area of the law, which worries me given the current SCOTUS.

The same SCOTUS that shot down Trump's similar attempts to hide his tax returns?

Also can't see Gorsuch voting for such a wide interpretation of executive privilege. So assuming Roberts doesn't either, there you have it.
